ERROR: [TTN] Connection to server "bridge.eu.thethings.network" failed

Please help!
I have Rak831 with raspberry pi 3b+. It worked perfectly for few weeks. Now I wanted to run it again and I got message “ERROR: [TTN] Connection to server “bridge.eu.thethings.network”” on Balena.io

Found this this thread, added ROUTER_MQTT_ADDRESS environment variable to mqtt://bridge.eu.thethings.network: 1883 but without success.

Any other ideas how to temporary fix it? Is this because of V2 migrating to V3?
I just need it till 15 of july.

Hello @jpurg ,

Have you tried checking the connection manually as suggested in the thread you shared? Also, did you change/update anything before it stopped working?

Cheers,
Nico.

Hello @jpurg as I replied you on reddit LoRa channel TTN v2 is sunsetting and you will need to move to The Things Stack v3.

What project are you using? Did you try https://github.com/balenalabs/basicstation ?
