Thanks for the feedback @El_Hereje and for letting is know of your delta error codes. Is there any particular numbered Delta error code that you see? We have a list of known Delta's here > https://support.ubisoft.com/en-GB/Faqs/000041460
I have looked into this investigation and it appears we have implemented something in the background to try and fix players being connected to the wrong data centre.
If you are now experiencing this issue come July, please let us know what your regional location is, what server you are being connected to and what ISP you use, so we can forward this along to the team implementing a fix.
