Subject: Request for Help: 504 Gateway Timeout After Authentication – MediaWiki 
1.34.4 with PluggableAuth + SimpleSAMLphp

Dear MediaWiki Support Team,

We are currently facing an issue with our MediaWiki instance and would 
appreciate your assistance in diagnosing and resolving it.
Issue Summary :
After completing the SAML authentication process, the application redirects to:
https://fssfed.ge.com/fss/idp/wSxxI/resumeSAML20/idp/SSO.ping
This URL loads for about a minute and then results in a 504 Gateway Timeout 
error. The final redirected URL when the error occurs is:
https://wiki.apps.domain.net/wiki/Special:PluggableAuthLogin

System Information :
MediaWiki Version: 1.34.4 (ff6464d)
PHP: 7.4.33 (fpm-fcgi)
MySQL: 8.0.35
ICU: 74.2
Elasticsearch: 6.8.23
LuaSandbox: 4.1.2
Lua: 5.1.5

Authentication Configuration :
We are using the following extensions for authentication:
PluggableAuth
SimpleSAMLphp

This issue started recently and prevents users from logging in via SAML. We 
have verified that our IdP is reachable and functional independently.

Request :
Could you please help us troubleshoot this issue or point us to any 
logs/configurations we should specifically check? Any guidance or 
recommendations would be greatly appreciated.

Thank you for your time and support.

Regards,
Akshay Sawade
