Well I don't think VPN will be the last option considering the fact that using a VPN could greatly affects the game processing since quit alot of data will be required to run an external VPN and this can affect the overall gaming experience in a negative ways, since it slow down you network and even eat dip into your internal device processing system.
Network connectivity issues are the least of the problems of using a VPN for accessing a casino platform. The biggest issue in using a VPN for accessing a casino when your country is restricted is that if the casino asks for KYC verification in the future or when you make a deposit or request a withdrawal, you won't be able to comply with that because all this time, you have been hiding your IP address but now you can't hide your identity since you are asked to submit your personal documents to comply with KYC and AML regulations.
I'm starting to wonder if reaching out directly to the casino's support team might be a better option. Perhaps they could provide more specific information about why my account is restricted and if there's a way to resolve the issue without using a VPN. I'll give it a shot and see what they say.
I feel like compliance with local laws and the recent crackdowns here in the Philippines might make that process a bit more complex, especially with foreign operators under scrutiny.
Reaching out to the support is probably your best shot. Don't use a VPN to access a platform if local laws in your country are against gambling or the casino doesn't support your country because you can get in trouble at the time of completing your KYC verification in case you manage to win something good and decide to make a withdrawal.
