VPN Instability

Does anyone else experience nearly constant instability of their VPN connection? I’m a VIP+ member but also had this problem as a free member. It seems that every 15 minutes I lose connectivity and need to reset my VPN. I’ve opened multiple tickets with support, but they are overly eager to close them as soon as the connection starts working (which it always does after a restart).

My network connection is otherwise stable. I regularly access other hacking labs and have only had this problem with HTB. Would love to know if other people have had this problem. Thanks.
