UK Freeview Guide Channel Logos Vanished

Hi all,

Got a small problem with my Channels DVR. Setup is HD HomeRun and Pi 4 DVR server. I've searched and found a few similar sounding posts but none of the solutions seem to work in my case. Everything was working perfectly until yesterday when the channel logo and name vanished from the guide on all devices. As a result it's rather hard to navigate the guide. Looks to me like the server providing the channel logos might have changed address or gone down? Checked on the HD Homerun App and channel lineup is all ok there so the problem is with Channels DVR.

I've tried redownloading the guide, refreshing channel lineup and all the options shown in the web config (see screenshot) but nothing seems to fix it! Anybody else with the same issue or an idea how to fix it? Thanks a lot!
