[BUG] Reconnecting error when calling on SIgnal #469

Open letmutx opened 2 years ago

letmutx commented 2 years ago

Whenever I place a call or get a call on Signal, dns66 is automatically disabled with a message saying "Reconnecting error" and I have to manually restart it. I see this error message in logcat when this issue happens.
