Hello. This is my first time I installed Virtualmin on an entry level VPS.
After a couple of effort I managed to set the server (dns records , roundcube , Lets encrypt etc) and host two domains on two subservers.
The issue I have is that my domains sometimes (not all the times) arent reachable. Browser message is “server not found”.
When I hit browser refresh 3-5 times all of sudden domains appear normally and they seem to work .
I am wondering what I am doing wrong. Is it a DNS records issue or a poor Server? or sth else?
Meanwhile server is up all the time cause even when my domains are down I can login to Virtualmin using the IP the provider gave me.
If server is up, then it’s down to you having a poor internet connection, assuming your domains have been propagation at least 48 hours…
Do you monitor the server IP with a third party to be sure the DC is experiencing any issues?
I registered and set up my domain’s DNS a month ago so I think its not a propagation issue.
My Internet Connection is good because I dont experience any issues at all browsing the web etc. Further more at the same time my domains arent reachable I can browse the web normally.
So About the domain Controller can you suggest me any tool to use?
Thank you for your replly
If your absolute sure it is not your ISP, then the fault might be at your DC. or between your ISP and DC,
I am using a Linux distribution, and use traceroute to see my ‘route’ [from ISP to DC] in Windows i believe it is tracert.
Then the most simple command is ping [yourserverip] and just let it run and check in other screen what happens if you do things on your server.
Ping ip > check.txt will create a file you can check later in time, for example if you have to leave your desk for a while…
If you suspect your DC, then contact them to discuss the matter as it might be something simple.
Another reason to contact your DC is to let them check your VSP if you rent it from them.
You can always consider a third party to monitor your VPS IP, I use several different ones to be sure to get alerts on my phones and emails.
There are some free ones as well, just Google.
Hope that helps.
