502 in UMC
Last modified: 2015-06-05 11:22:20 CEST
We saw the 502 timeout several times in several UMC operations... on nearly any case it is sufficient to do the same job at cmd - for example an update. I have no idea if this helps, but we could create a sdb article for this "known error" and describe it - like microsoft does with most common "error" messages.
This luckily only was a short period of occurence ;)
