  • Maybe ipv6 DNS issues:

    
    ;; ANSWER SECTION:
    www.rebeltechalliance.org. 159  IN      CNAME   rebeltechalliance.org.
    rebeltechalliance.org.  158     IN      A       136.243.169.53
    
    ;; ADDITIONAL SECTION:
    rebeltechalliance.org.  159     IN      AAAA    2a10:e000:1::10
    
    

    I’m not completely up to speed on ipv6 stuff but I can’t get that AAAA address to resolve. If it is a valid address you may be running services only on ipv4 and the VPN could be using an ipv6 address where no programs are listening… I think?

    Also if you run the whole host you may want to see if you need all of these services available or can block incoming connections to them.
