Q: How long does DNS propagation take?
A: Changes reach NimbusServe nameservers within 5 minutes. Global
propagation across all ISPs takes 2 to 48 hours. Lower TTL values
speed up propagation. Set TTL to 300 (5 minutes) before making
changes if you need faster propagation.

Q: How do I point my domain to my hosting?
A: Create an A record in the DNS management panel pointing to your
hosting server’s IP address. For NimbusLite hosting, use the IP shown
in cPanel. For NimbusCloud VPS, use the server IP from your setup email.
Alternatively, change nameservers to ns1/ns2.nimbusserve.com if your
hosting is also with NimbusServe.

Q: How do I set up email DNS records?
A: Add an MX record pointing to your mail server. For NimbusSaaS email
hosting, use: MX record with value mail.nimbusserve.com priority 10.
Also add SPF (TXT record: v=spf1 include:nimbusserve.com ~all),
DKIM (provided in email hosting setup), and DMARC records.

Q: How do I enable DNSSEC?
A: Go to the DNS management panel > DNSSEC tab > Enable. The DS records
are published automatically within 15 minutes. No manual configuration
is needed for domains using NimbusServe nameservers.

Q: Can I register a domain without buying hosting?
A: Yes. Domain registration is a standalone service. You can register
any domain and point it to any server or hosting provider using DNS
records or nameserver changes.

Q: How do I set up a subdomain?
A: In the DNS management panel, create an A or CNAME record with the
subdomain prefix. For example, to create blog.yourdomain.com, add
an A record with name “blog” pointing to your server IP, or a CNAME
record pointing to another domain.

Q: What happens when my domain expires?
A: Domains enter a 30-day grace period after expiration. During this
period, you can renew at the standard price. After the grace period,
domains enter a 30-day redemption period with a 99 redemption fee.
After redemption, the domain is released for public registration.

Q: Can I get a refund on a domain registration?
A: Domain registrations are non-refundable because the registration
fee is paid to the registry. Exceptions may be made within 5 days
for accidental duplicate registrations. Contact support for review.

Q: How do I protect my domain from unauthorized transfer?
A: Domain locking is enabled by default on all NimbusServe domains.
When locked, transfer requests are automatically rejected. You can
manage the lock status in the client area under Domains > Your Domain
> Security.

# Common Troubleshooting

## Overview
This skill covers the most frequently reported technical issues across
all NimbusServe service lines. Each issue includes a step-by-step
troubleshooting tree that the agent follows to guide customers through
resolution.

## Issue 1: 502 Bad Gateway

### Symptoms
Customer reports seeing “502 Bad Gateway” when visiting their website.

### Resolution steps
1. Ask the customer if they recently made any changes to their website
   (plugin updates, code changes, .htaccess modifications).
2. Check if the issue is on a specific page or the entire website.
   If specific pages, it may be a PHP error in that page’s code.
3. For shared hosting (NimbusLite): The PHP-FPM process may have hit
   memory limits. Suggest the customer check cPanel > Error Log for
   PHP fatal errors. Common cause: a plugin or theme consuming too
   much memory.
4. For VPS (NimbusCloud): Ask the customer to check if their web
   server process is running (systemctl status nginx or apache2).
   If not running, suggest restarting it.
5. If a reverse proxy (Cloudflare, Nginx) is in front of the origin
   server, the 502 may be from the proxy unable to reach the origin.
   Ask if they use Cloudflare and suggest temporarily pausing it to
   test direct access.
6. If none of the above resolves the issue, escalate to the support
   team with the information gathered in steps 1 through 5.

## Issue 2: SSL Certificate Errors

### Symptoms
Customer sees “Your connection is not private,” “NET::ERR_CERT_AUTHORITY_INVALID,”
or similar browser warnings.

### Resolution steps
1. Ask the customer which domain shows the error and what browser
   they are using.
2. Check if the SSL certificate has expired. Free Let’s Encrypt
   certificates auto-renew, but renewal can fail if DNS is
   misconfigured or the server is unreachable on port 80.
3. For shared hosting: Suggest the customer go to cPanel > SSL/TLS
   Status and check if the certificate shows as valid. If expired,
   click “Run AutoSSL” to trigger renewal.
4. For VPS: Ask the customer to run “sudo certbot certificates” to
   check certificate status. If expired, run “sudo certbot renew”
   to renew.
5. If the domain recently changed DNS, the old certificate may not
   match the new IP. Wait for DNS propagation to complete and then
   request a new certificate.
6. Mixed content errors (some resources loaded over HTTP instead of
   HTTPS) cause padlock warnings but not full certificate errors.
   Suggest checking the browser console for mixed content warnings.

## Issue 3: DNS Not Resolving

### Symptoms
Customer reports their domain is not working, shows “DNS_PROBE_FINISHED_NXDOMAIN”
or “Server not found.”

### Resolution steps
1. Ask the customer when they last changed DNS settings or nameservers.
2. If nameservers were recently changed, explain that DNS propagation
   takes 2 to 48 hours. Suggest checking propagation status at a
   public DNS checker tool.
3. Verify the domain has not expired. Expired domains stop resolving.
   Ask the customer to check their domain status in the NimbusServe
   client area under Domains.
4. If using NimbusServe nameservers, verify that the correct A record
   exists in the DNS management panel pointing to the hosting server IP.
5. If using external nameservers (Cloudflare, Route53), the DNS records
   need to be configured at the external provider, not in the NimbusServe
   panel.
6. For recently registered domains, DNS resolution can take up to 24
   hours after initial registration. This is normal.

## Issue 4: Email Delivery Issues

### Symptoms
Customer reports emails are not being received, going to spam, or
bouncing back with error messages.

### Resolution steps
1. Ask the customer if they are having issues sending, receiving, or both.
2. For emails going to spam: Check if SPF, DKIM, and DMARC records are
   configured. Missing or incorrect records cause spam classification.
   The correct SPF record is: v=spf1 include:nimbusserve.com ~all
3. For bouncing emails: Ask the customer for the exact bounce message.
   Common causes include full mailbox, invalid recipient, or blacklisted
   sending IP.
4. For emails not being received: Check if the MX record is correct.
   It should point to mail.nimbusserve.com with priority 10.
5. For sending failures: Verify SMTP settings. Server: mail.nimbusserve.com,
   port 465 (SSL). Common cause: wrong port (some clients default to
   port 25 which is often blocked by ISPs).
6. If the sending IP is blacklisted: Check at mxtoolbox.com/blacklists.
   If listed, submit a delisting request. This typically resolves within
   24 to 48 hours.

## Issue 5: Slow Website Performance

### Symptoms
Customer reports their website is loading slowly or timing out.

### Resolution steps
1. Ask the customer when the slowness started and if anything changed
   (traffic spike, new plugin, large file upload).
2. For shared hosting: Check cPanel > Resource Usage to see if CPU or
   memory limits are being hit. If limits are consistently reached,
   suggest upgrading to a higher NimbusLite tier or NimbusCloud VPS.
3. Suggest testing the website speed at GTmetrix or Google PageSpeed
   Insights to identify specific bottlenecks (large images, unminified
   CSS/JS, no caching).
4. For WordPress sites: Recommend installing a caching plugin (WP Super
   Cache or W3 Total Cache) and optimizing images with ShortPixel or
   Imagify.
5. For VPS: Ask the customer to check server resource usage with top
   or htop. High CPU or memory usage from specific processes can
   indicate a runaway script, database query, or attack.
6. Check if the server location (Frankfurt) is geographically far from

## Issue 6: Database Connection Errors

### Symptoms
Customer sees “Error establishing a database connection” on their website.

### Resolution steps
1. Ask the customer if the error appeared suddenly or after making
   changes to their website configuration.
2. For shared hosting: The MySQL server may be temporarily overloaded.
   Suggest waiting 5 minutes and refreshing. If persistent, check
   cPanel > phpMyAdmin to verify the database is accessible.
3. Verify the database credentials in the website configuration file
   (wp-config.php for WordPress, .env for Laravel, config.php for
   custom applications). The database host, name, username, and
   password must all match.
4. For VPS: Ask the customer to check if MySQL/MariaDB is running
   with “systemctl status mysql” or “systemctl status mariadb”.
   If stopped, restart with “sudo systemctl restart mysql”.
5. If the database server is running but connections fail, check if
   the maximum connection limit has been reached. This happens during
   traffic spikes. For shared hosting, this limit is set by
   NimbusServe. For VPS, the customer can increase max_connections
   in the MySQL configuration.
6. If credentials are correct and the service is running, the database
   may be corrupted. For WordPress, suggest running “wp db repair”
   via WP-CLI or adding “define(‘WP_ALLOW_REPAIR’, true);” to
   wp-config.php temporarily.
