Web Player / webGL builds hang, Android is fine

Unity Services
1

I recently tried out the Unity Cloud Build service and am having some trouble with the Web Player target. Android works fine and takes about 5 minutes to complete the build. On Web Player, the build runs for almost an hour, then gets stuck and cancelled.

When I check the logs to see what’s going on, it seems like the build is hanging in some ‘CheckConsistency’ steps. I don’t have the same issue locally and the messages are vague, so it’s difficult for me to fix the issue.

Has anyone seen issues with Web Player builds hanging?

Usually when the build hangs, I see a bunch of messages like this in the logs (repeated dozens of times with small variations):

On a related note - how do build times for mobile targets like Android compare to Web for other people? I’m still surprised that Android takes around ~5 minutes and Web is taking > 60 minutes before erroring out. Is this in line with what other people see when building web?
