"Trying to connect with server" error

Question

I'm having difficulty syncing my Lightroom Classic, under local activity it just says "Trying to connect with server". All of my other Adobe apps are syncing well, and I'm able to select the edit in Photoshop option and have the images automatically opened there to edit.

I have been through all of the threads that I have found on the issue, but so far haven't been able to fix it.

Likely related is a pop up "Revocation information for the security certificate for this site is not available" error when using LRC, but again following the suggested tutorials hasn't solved this issue either.

Hi Theo,

Found resolution to this issue in my laptop. If you are running Lightroom on Windows 11 (might be issue also in older version) try this one. It fixed my issue.

Internet options / Advanced tab and scroll down to Security section. "Check for publisher's certification revocation" tickbox must be empty.

I have a dim memory that I have emptied this tick box in the past for same reason. It might be that some Windows security update has changed that setting.

Best regards,
