Timeout
It did not finish within 3, 5 or 10 seconds. Verify host and port, try a stable network, then check firewall and service status.
SUPPORT / TROUBLESHOOTING
Turn an error into a useful next step.
Resolve import, timeout, DNS, TCP, TLS and VPN problems.
DNS failure
Remove URL paths or spaces from the host and retry on another network. If an IP works but the name does not, check resolver or DNS records.
Connection refused
The host was reachable but the port did not accept, or a firewall rejected it. Confirm port and service status.
TLS failure
Confirm the target offers TLS, then check hostname, certificate dates, proxy and server protocol.
Import failure
Follow the error and check UTF-8, 1 MiB limit, required sections, keys, endpoint, embedded OpenVPN material and duplicates.
VPN will not connect
Check network, endpoint, certificate and credentials; disconnect before switching. Ask the third-party server operator about status.
