"Unable to login to server" error when performing a web restore

This article applies to CrashPlan PROe version 4.

Other available versions:

Version 6 | Version 5icon.qnmark.png

Overview

When accessing the administration console over HTTPS, web restores from storage servers may result in an "Unable to login to server" error. This is usually due to a self-signed or invalid SSL certificate on the storage server and the need to manually accept this certificate when connecting to the enterprise server.

Affects

CrashPlan PROe administration console version 3.x and later

Recommended solution

Long-term secure fix

Install CA-signed certificates on each of your storage servers. A properly signed certificate prevents the web browser from prompting the user to accept the unsigned certificate.

If you already installed CA-signed certificates on each storage server, verify that the storage server's hostname matches the name in the certificate.

Short-term workaround

Sign in to the admin console on each storage server

Connect to the administration console on each of your storage servers over HTTPS on port 4285 and accept the self-signed certificate.

When connecting to the enterprise server directly, your browser should prompt you to either temporarily accept, or permanently add an exception, for the certificate.

Once the certificate is added to the exception list in the browser, web restores should function normally even when connected to the master server over HTTPS.
