upgraded vmanage from 20.3.2.1 to 20.3.3.1 , and started seeing this error. Is there any workarounds or solutions? diagnostics did not revel anything.

My vManage was working fine until last week. Now I'm facing same issue - upstream connect error or disconnect/reset before headers. reset reason: connection failure
vManage version 20.3.3

i never found a solution for this, i got lucky with one of these options: if you have old snapshots use it/ do cold reboot/ power cycle, to see if it works. if it works, my advice is to upgrade to 20.6.3, it is much stable.

I found out that the disk size was full due to which getting error. It was due to a monitoring tool which was freshly deployed. Now the issue is resolved. Please check on vShell used space in /dev/sdb drive.

Just replying with how I managed to fix this issue, if anyone else comes across this.
TAC just told me to upgrade, even though I sent them df -kh outputs that clearly showed /rootfs.rw was 90% full
That is not going to work, and actually is the root cause of the webserver failing.
logs show that if you have less than 1GB free on /rootfs.rw the application server shuts down. causing the error.
turns out I had a ton of old logs filling up the disk.
the culprit is these files: /rootfs.rw/var/volatile/log/nms/vmanage-elastic-cluster.log.*
they are not auto cleaned and fills up the disk.
Deleted them and restart nms all, and suddenly everything worked.
NB: Upgrade will fail if you have less than 50% free space on /rootfs.rw as well.
So just delete those old logs and make sure you got more than 50% free diskpace and you should be fine.
