Web ui won't accept connections from sonarr after reboot

[tugurlann]

I'm running deluge on a ubuntu machine alongside sonarr.

I have noticed that the sonarr app cannot connect to the web ui interface without me manually connecting one time to the web interface via the browser and selecting the one (and only) available connection.

If i don't do that, sonarr complains it can't connect to web ui.

Once I do it once, it works as expected and can communicate with deluge.

Would that be a deluge or a sonarr problem, has someone else encountered this problem?
