Different problems, install and not latest version

[monkeyfella]

I am trying to use shoutrrr with watchtower, watchtower runs in docker.

Installing shoutrrr through snap does not install the latest version, it's 0.7.1

and trying to install with golang it says "package github.com/containrrr/shoutrrr is not a main package"

And running watchtower I have gotten the shoutrrr service to work initially, but the container almost directly get status "unhealthy" and it says "level=fatal msg="Failed to initialize Shoutrrr notifications: error initializing router services: failed to log in: Too Many Requests\n"

I am trying to send a message through matrix and have set up the url "matrix://user:password@chat.url.com/?rooms=!roomid:chat.url.com"

and it initially connects and sends the message that it will update in 24h but then directly goes to unhealthy.
