[Wikitech-l] Re: Request for Help: 504 Gateway Timeout After Authentication – MediaWiki 1.34.4 with PluggableAuth + SimpleSAMLphp

1.34 is ancient and end of life/end of support many years ago and likely has known unpatched security vulnerabilities. Try updating and see if it occurs on a more recent and supported version of MediaWiki such as 1.43 LTS or 1.44.

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
