You may receive the following error message in a web browser when connecting to an outdated and unsupported version of VisualSVN Server:
Google Chrome, Microsoft Edge and other Chromium-based browsers
Due to TLS 1.0 and TLS 1.1 deprecation, modern browsers can only connect to servers that support TLS 1.2 or higher. VisualSVN Server supports TLS 1.2 beginning with version 3.2.0. Versions older than 3.2.0 do not support TLS 1.2.
You should upgrade the VisualSVN Server installation to a newer version to solve this issue.
Up-to-date versions of VisualSVN Server support TLS 1.2 and TLS 1.3. Upgrading the server to the current version will resolve the issue and web browsers will connect without errors.
