Hi Team,

Currently I’m using Jenkins 2.346.3(LTS) version and we have hosted Jenkins war file on top up Tomcat server(9.0.4)…
Issue:- In Manage Jenkins page → Assign Roles ----> if i do any changes and click save and apply button I’m getting error below,

Type:- Status Report
Message:- no valid crumb was included in the request
Description:- The server understood the request but refuses to authorize it.

due to this i’m unable to save changes on Manage Jenkins page.

I have tried these options but didn’t resolve my issue.

  1. removed deprecated and warning plugins
  2. upgraded the plugins and Jenkins versions upgraded
    3)Few plugins installed(Strict Crumb Installed)plugin and tried the options

Can anyone please let me know solution for this. Thanks.

Are you using the active directory plugin?
