| I have the same problem using the release 2.176.1 I can't say if the problem is new since my recent update, since I didn't upgrade plugins for a while. I have to instances of Jenkins, both on 2.176.1 :
- the first one is checking updates whitout any problem. I could see that the called URL is /pluginManager/checkUpdatesServer.
- the second one hangs on /pluginManager/checkUpdates. On this one the requested URL is /pluginManager/checkUpdates.
Why is the link different on these two instances of the same Jenkins release ? When I change the requested URL on the second one to /pluginManager/checkUpdatesServer, all works fine and i can see the available updates. |
