Troubleshoot internet issues

Read this page if ConEmu internal automatic update fails to download current version information or distribution packages most probably there are issues with your Internet Explorer, because ConEmu utilizes standard Windows API from wininet.

Possible ways to solve the problem are described below.

Change version.ini location

At the moment there are several maintained locations of version.ini:

If your provider/proxy/router blocks, for example, an access to default https://conemu.github.io/version.ini you may try other locations from the list.

If all these locations are inaccessible from any browser on users PC, there are no options. User have to contact their network administrators for assistance.

Otherwise please open Settings/Update and paste into the ‘ConEmu latest version location info’ working URL. Don’t forget to save the settings.

Update Internet Explorer

Try to open https://conemu.github.io/ in the Internet Explorer (not in your default browser). If it can’t open the site, try to update your Internet Explorer.

There were reports that after updating from 8.0 to 11.0 the problem with https access were solved.
