None of these messages will help, please read How to troubleshoot WireGuard for more information.
Try using another wireguard client on a separate device to connect to the server to rule out an issue with the AXT1800 client.
Disabled Parental Control and Virus Safe settings on ISP provider settings and restarted the wireguard. It went successful this time.
The concern here is that why do I have to disable these important settings for the VPN to work?
First of all I think these two functions are related to network traffic, packets, IP/ports, etc.
To be honest: "Virus Safe" settings by ISP are mostly bullshit you pay for. It won't protect your endpoint and yeah ... wouldn't recommend it.
Since VPN will be used to break through both protections, I would assume your ISP blocks it. Furthermore, this means your ISP is doing Deep Package Inspection, which is something even more concerning in my opinion.
