Symptoms
- You start Acronis True Image.
- You provide credentials to your Acronis account.
- Signing in fails with error:
An error occurred while signing in. Please try again later.
Cause
TCP port 443 is blocked on your computer or router.
Solution
TCP port 443 is required to secure your communications in Internet over TLS/SSL. Acronis True Image uses secure connections when signing in and requires port 443 to be open.
You can check the port's status by using Acronis connection verification tool or by check it with telnet.
Open TCP port 443 for outbound connections in Windows firewall (see this Microsoft article for instructions). If the port is blocked by a third-party firewall or on your router, you need to open it there.
More information
If you have checked the port with the telnet command or the connection verification tool and the port is open or the problem persists after opening the port, please collect the following information and contact Acronis Customer Central:
- Wireshark log capturing the problem: start Wireshark, then start Acronis True Image and try to sign in, wait until the error appears, then stop Wireshark, save the log.
