If the platform you intend to play from has not listed your country on their site as a blacklisted location, usually they advise you try to either change browser or clear your cache memory... If not try check that you aren't using a VPN which could be restricting your access to the platform... Sometimes if the casino has intergrated cloudflare this is the culprit denying you the access.
I will not try to access that platform because I do not want to get a problem. The casino is already restricting our access, so we should not keep trying to access their site while there are more gambling sites that we can use to gamble. It is better to play safe and not risk ourselves on the casinos that don't allow us. Perhaps, asking their support system is a good idea to know why we can't access them. Using VPN is in the grey because some casinos will not allow us to use it.
