Many times a day get EAI_AGAIN error while trying to connect to ftp://files.000webhost.com (with FileZilla). After 10-60 minutes everything becomes OK.
Site is offline during this error (Chrome says “DNS_PROBE_FINISHED_NXDOMAIN”), but works via proxy (browsec addon).
Thinked it is DNS problems, but using google DNSes (8.8.8.8, 8.8.4.4) and “ipconfig/ flushdns” command have no effect.
Your website works fine, atleast here…
Any screenshots please 
thanks for the extensive info so far
The error haven’t appeared for days. Everything is OK right now 
Hmm not sure what to say there isn’t anything in the last week that would suggest any issues on our behalf that would cause this.
As above you’ve used alternative DNS, try other alternative DNS in the meantime or make sure you are using ipv4/6 both alternatives at once, full DNS flush the cache and hopefully it clears up without the need for a proxy.
Depending on your provider, home or work or educational place they can have their own DNS pushed at the end so using alternative won’t make a bit of difference sadly but normally it does work, if you are at home you could take a quick peek at router settings normally http://192.168.0.1 or http://192.168.1.1 just view your network connection, status, gateway and go to that address, login admin admin or similar combinations normally written on the router and see if there is DNS option to change in the router itself.
Failing that, power cycle your router in the hopes you’ve got a dynamic IP address and get a new one to see if that solves the issue without having the need to use a proxy.
