A while after kicking off the SDDC Manager 5.2.1.0 upgrade I was presented with the nginx error “502 Bad Gateway” in my browser. Thinking that this was caused by the services being restarted as part of the upgrade I waited 15 more minutes but the error would not go away like it use to. Checking the log files on SDDC Manager didn’t show any progress and lcm-debug.log halted after this:
2024-10-25T06:23:02.415+0000 INFO [vcf_lcm,0000000000000000,0000] [com.zaxxer.hikari.HikariDataSource,SpringApplicationShutdownHook] HikariPool-1 - Shutdown initiated...

After waiting for another hour I figured that the appliance was supposed to reboot but didn’t manage to, so I rebooted it manually. After it was back up I was presented with this nice status page showing that it had expected a reboot to happen (Reboot SDDC Manager).
After about 10 more minutes the upgrade completed.
