In the morning, Unity Hub 3 clicked to log in and did not respond (the key did not respond and there was no prompt!), as follows:
Then, I tried various methods on the Internet: deleting the cache folder, reinstalling HUB, resetting the default browser, and so on. None of the results work. Then calm down and start analyzing the log of HUB, and finally it worked.
Solution: Analyze HUB logs. See which step is wrong.
Right-click HnityHub on the taskbar to open the log folder, as shown in the figure:
Open the log file. My default opening method is vs code, which can dynamically load the changes in the log:
After opening the log file, operate the unity hub, click [Login], and you can see what happened after the click. My error here is that the HUB requested the address on the map, but there was no response.
Run this error URL in the browser, and after confirming that you can connect, it’s ok~
This time it also reminded me that if I can't log in in the future, I can look at its log and analyze where it is stuck.
