Alfresco Share Login Error after updating SSL certs

I am using Alfresco standalone community edition on Ubuntu Machine which is working with configured domain. SSL certs are going to expire in a week so I update the new domain crt and keys in nginx.conf After updating while login to share getting below error but old domain is still active and able to login to share even new domain certs and keys are configured.

Something's wrong with this page...
We may have hit an error or something might have been removed or deleted, so check that the URL is correct.
Alternatively you might not have permission to view the page (it could be on a private site) or there could have been an internal error. Try checking with your IT team.

    }
}
}

Gone through the similar cases in web some are suggesting to change the parameters like port number and proxy pass, server.xml changes. May be i am wrong But my question is the setup working fine for 1 year after updating new domain certs getting share login errors.

Don't whether the old certs are stored or cached as share is accessible through old domain even updating nginx.conf with new certs.

Any ideas or suggestions would be a great help Thanks

Your error happens in Alfresco itself and has nothing to do with certificates. If you check the correct log (tomcat/logs/catalina.out) you should see your issue.

My guess is that you use a different hostname than configured and that fires the CSRF Token Filter in Alfresco Share.

Either change the share.host and alfresco.host in alfresco-global.properties or disable or modify the CSRF Token Filter in share-config-custom.xml
