Adding dns with non-standard port causes the app to close and to never come back

[menkaur]

I'm running my own dns server, and I'm exposing it to yggdrasil on port 55 (tested, working correctly).
I decided to try and use it in the app
I entered my pc's address followed by ::55. After this, I have connected to yggdrasil network. The outcome is that the app stops to function and the only way to revive it is to wipe the data. I'm assuming this is because I'm using non-standard port, but I'm not sure

App version: 0.5.4.1
