WebUI Connection Troubleshooting• Issue: Browser SSL Errors (e.g. ERR_SSL_PROTOCOL_ERROR)

• Happens mostly due to stale Self-Signed Certificate

• Recovery Steps: Regenerate Self-Signed Certificate

• Disable NGINX Server using ‘conf term’ → ‘no ip http secure-server’

• Remove Self-Signed Certificate

• Find using ‘show run | include crypto pki trustpoint’

• Remove listed cert using ‘conf term’ → ‘no crypto pki trustpoint <certID>’

• Verify removal using ‘show run | include crypto pki trustpoint’

• Enable NGINX Server using ‘conf term’ → ‘ip http secure-server’

• Verify new Self-Signed Certificate using ‘show run | include crypto pki’

• Save config, reload using ‘write mem’ → ‘reload’

• Once Router is reloaded try to connect to WebUI, “https://<Router-ip>:443”
