can't upgrade tl-sg2210p to 5.0.3
Hi all, I found this thread here but it got locked (I assume due to someone's naughty language and inability to be civil):

I am having pretty much the same issue - my switch fails when trying to ugprade to 5.0.3
I run my own software controller (latest version, just set it up a couple weeks ago) offsite so I have NATs set up for udp 29810 as well as tcp 29811-14
This seems to work just fine generally for discovery and configuration, but not this fw upgrade.
Any suggestions welcome - thanks!
