About hub, an unknown connection type occurred

[LiangKuo]

I have a client who installed Qlik Sense Enterprise Edition February 2022 Patch 15.14.54.2. After launching the hub, he clicked on one of the apps and then clicked on Data Download. Then, on the right side of the screen, the data connection said connection unknown. After removing the patch, everything returned to normal. How can I explain this?   p.s There is an error message in the event viewer

Hi LiangKuo, due to the changes in patch 15, I would suspect that the issue was caused by the header size. I would suggest the following articles:
