The fact that restarting the server resolves the issue temporarily suggests that there could be a memory leak or configuration issue or some other resource issue that is causing the server to become unstable over time.
Here are a few additional things you can try to troubleshoot the issue:
- Increase the heap size of the JVM. This may help to mitigate the memory leak or resource issue.
- Analyze the JVM heap dump. This can help you to identify any specific objects or threads that are consuming a lot of memory or resources.
- Enable garbage collection logging. This can help you to identify any garbage collection issues that may be contributing to the problem.
- Monitor the server performance. This can help you identify any spikes in memory usage, CPU usage, or disk I/O that may be causing the server to become unstable.
- Enable debug logging for the AEM Dispatcher and the AEM Web Server. This will generate additional log messages that may help you to identify the root cause of the issue.
This is worth a case to be reported to Support. As this requires debugging. I would like to route you through Support team.

Possible causes:
- The PRD-publish server may not be able to communicate with the API server.
- The Servlet may not be deployed to the PRD-publish server.
- The Servlet may not be configured correctly to access the API.
- The API may not be accessible from the PRD-publish server.
- The PRD-publish server may not have the same security configuration as the PRD-author server.
- The PRD-publish server may not have the same network configuration as the PRD-author server.
Additional check/Tips:
- Make sure JDK versions match
- Make sure Trust Store and Key Store configurations match
- Check AEM error logs
- Restart AEM PRD-publish server and API server
- Make Sure they have the same security configuration

can you please check the response headers. It seems the connection to api is not establishing?
Compare the header when you make request from postman and with servlet.

As you have tried the other options, I would suggest to talk to Adobe CSE and request to provide a clone of the publish server for a week or two in the same network region as your currently publish instances are. While the clone is provided, request to
1) Disable all the schedulers that are set to run daily/weekly etc.,
2) Reset admin password on the clone instance to something else other than the current admin password.
3) Ability to SSH into Prod publish clone instance.
After you get a clone instance, you can enable more logging and discover any connectivity issues to API servers from this clone by running curl commands to the API urls and making sure there are no network connectivity issues.
