Unable to connect to Trakt on my Firestick 4k

I have been using Series Guide on my Fire TV for some time and although it’s Trakt integration is a bit flaky I have overall been happy with it. Now I have just got a Firestick 4k and I am completely unable to connect to Trakt. I have tried Firefox and Silk browsers and the internal browser and I just get a variety of different errors.

Welcome! This is a known issue without solution, sorry.
