GTmetrix Error 520 since renew SSL

[Reinhard Jung]

Hi @ll

After moving all DNS-Record to Litespeed = GTmetrix was working (D/F)

The last thing i did was updating SSL, then GTmetrix displays this Error:
"The page returned an error: 520 Origin Server Unavailable"

Any Idea on how i can fix it? :-(
Thanx a lot for any hints...

A bit more information please.
Which kind of web server do you use? OLS or LSWS? Do you use quic.cloud? Which cache plugin do you use?

Well. The Issues was that the IP as somehow changed and i had to update it :-(

Now everythind is working fine exept the Cache itself :-(

Whenever you check your page at Pagespeed or any other test sites, check before if to be tested page is already cached, but note Pagespeed doesn't check the loading time. It only tests the "display time". There is big difference.
