core: Unable to setup Environment Canada integration

The problem

I’ve been trying to set up the Environment Canada integration for my city but I’m unable to because I get a Cannot Connect error. I’ve tried giving no weather station id, giving one, removing the long and lat, etc. but no combination works for me. I entered the station id in all possible ways I can think of but as far as I’m aware this is the correct format for my location ON/s0000XXX where XXX is the 3 numbers for my location.

I feel like the error is implying that it’s a connection issue but I have the integration working on another system, except now I can’t add a new location to that system. The system that works is a VM on TrueNAS, and I tried setting up another VM on it but I can’t add the integration to the new VM, and I also tried adding it on a new install of HAOS on an Intel system (non VM) but that doesn’t work either.

I’m at a loss as to why I can’t add the integration anymore, and I don’t know what else to try because I can’t get any logs when setting up the integration. I’m also experiencing an issue with the Environment Canada integration that is set up showing unavailable most of the time so maybe it’s an issue with my internet (I’m going to do a separate issue report for this since trying to set up the integration on a new install of HA was part of my troubleshooting steps). But I don’t know what the cause of that would be since connecting to the API works on my computer and I can do a curl with TrueNAS and get data when it wasn’t working in Home Assistant.
