I can reproduce this issue locally but not on the official instance or when using the docker image.

How are you running rss-bridge?

I recommend switching a docker based setup if possible. See the link below for how.

I am currently running rss-bridge using the rssbridge/rss-bridge:latest docker image.

I am able to reproduce with the official instance here as well as local:

Looks like the channel can't be viewed or previewed outside of telegram's app.

I had the same thought, but I tried five different public channels, and they all produced the same result. Have you been able to get it working with any channel? I use RSS-Bridge with multiple channels, and they all stopped working around the same time, so I suspect something may have changed on Telegram’s side that is causing this issue.

Have you been able to get it working with any channel?

Yes. with rssbridge, telegram and a few others.
