My broker is not supported by VPS.

 
I attempted to register my MT4 account on a VPS provided by MQL4, but it did not work. I contacted my broker, who advised me to contact the VPS provider. Thr problem is no desk help for MQL
 
If you subscribed to MQL5 VPS so this information should be listed on this page: https://www.mql5.com/en/vps/subscriptions
If yes so connect MT4 to your trading account (MQL5 VPS is per trading account) and
synchronize the opened charts with EAs or signal subscription - read this post about HowTo.
After that - check the MT4 journal and MQL5 VPS journal to be sure that everything is fine (or if error so it should be written there).
