Causes Of Ah01985 Error
The AH01985 error happens when the web server cannot get a proper reply from the OCSP server. This usually means there is a problem with the Online Certificate Status Protocol check. The OCSP server helps check if a security certificate is still valid.
Common causes include network issues blocking the server from reaching the OCSP responder. Sometimes the OCSP server is down or not responding fast enough. Another cause is a misconfiguration in the server’s SSL settings.
Firewalls or proxy servers may also block the connection, causing timeouts. Incorrect URLs or expired certificates can lead to failed OCSP checks. These problems stop the web server from reading the OCSP response correctly.

Checking Ocsp Server Status
Checking the OCSP server status helps fix the AH01985 error. The OCSP server tells if a website’s security certificate is valid. If the server is down or slow, the error appears.
Start by testing the server’s connectivity. Use tools like ping or traceroute to see if the server responds. A failure means the server might be offline or unreachable.
Next, check the server’s response time. Long delays can cause your system to time out. If responses take too long, try again later or contact the server administrator.
Also, verify the server’s URL and configuration. Incorrect settings in your web server can cause errors reading OCSP responses.
Regularly monitor the OCSP server to ensure smooth communication. Proper checks reduce the chance of security errors.
Configuring Apache For Ocsp
Apache servers use OCSP to check if an SSL certificate is still valid. This process helps keep websites safe and secure. To configure Apache for OCSP, you need to add a few lines to the server’s configuration file.
First, enable OCSP stapling by adding SSLUseStapling on. Then, set the OCSP responder URL with SSLStaplingResponderTimeout and SSLStaplingReturnResponderErrors. These settings tell Apache how to ask the OCSP server and what to do if errors happen.
Make sure your server’s time is correct. Wrong time causes OCSP checks to fail. Also, check that Apache has access to the OCSP server URL. Without access, the server can’t get the response, leading to errors like AH01985.
Network Troubleshooting Tips
The AH01985 error means the server has trouble reading the OCSP response. This often happens when the network has connectivity issues. Check if the OCSP server is reachable by pinging its address. Firewalls or security settings may block the connection. Make sure ports used by OCSP (usually port 80) are open.
Slow or unstable internet can cause timeouts. Try restarting the router or switching to a faster network. Also, ensure your server’s date and time are correct. Wrong system time may cause SSL or OCSP checks to fail.
Sometimes, the OCSP server itself has problems. Wait a few minutes and try again. If the issue continues, contacting the service provider can help.
Alternative Solutions And Workarounds
Check your network settings first. Sometimes, a firewall blocks the OCSP server. Try disabling firewall temporarily to see if it helps.
Update your server software. Older versions may have bugs causing this error. Installing the latest updates often fixes issues.
Switch to another OCSP responder. Some servers offer multiple responders. Changing the URL might solve the problem.
Use CRL (Certificate Revocation List) as an alternative. It can verify certificates when OCSP fails.
| Solution | Description |
|---|---|
| Firewall Check | Temporarily disable firewall to allow OCSP server access. |
| Software Update | Install latest server patches to fix bugs. |
| Change OCSP Responder | Use different OCSP server URL for verification. |
| Use CRL | Employ Certificate Revocation List instead of OCSP. |
