Network login problem. After matches, network error occurs locking up and suggesting resigning onto the client. Closing and attempting to rejoin client yields "unable to get collection - log on later" Later, when?

I see that this has happened to many others after software updates in the last 6 months, but no suggestions as how to solve.

Uploading Crash Report
NullReferenceException: Object reference not set to an instance of an object

Same Issue for me - multiple desktop machines, mobile devices, tried on different networks

Same for me. Losing server after a few turns or start of the game. Or it just won't load at all. Also have gotten several different errors from authentication errors, network error, and collection error.

Same here (in Germany) since this morning . Laptop and phone (wlan). Interestingly enough: if I use my phone as wifi-hotspot for my laptop I can connect (but only then). Weird.

I hate how they don't care and let this go on for several months, support is not useful at all

Same error. Unable to get collection....

Same error. Unable to get collection ...

Problem yet not solved.

In the past, there was a rank bug that didn't increase. It took 3 months to fix it and didn't compensate anything. Come this time, I can't enter the game again. It's been a month and still can't fix it or don't care to fix it. I don't know. Poor support, service that doesn't care about customers at all.

Same error. Unable to get collection....

Same issue fix plzzz

I have had same issue and contact customer services to be told "Sorry can help you go look at technical bugs to see if someone managed to fix it" when its clearly an account issue as I tried to with both my laptop and my phone and both did the same. I done everything I can to try and get this to work and I am not so angry because I have lost 3 years of playing nearly daily, putting money in etc.

same issue.fix it plz

Same for me. When it happens, I cannot log in any of my accounts with different devices, network or vpns. But after a few hours, I can log in again.

Same for me, on mobile I keep losing the server, and can't loggin on PC

Been having this problem since Feb 27 (in the UK).
Really convenient timing given I have the Regional Championships next week to prepare for.

Happening since the new set for me since start of March. In the UK. Sometimes allows login, but often gives this error
