Unable to clone anymore from Openwrt

On the firmware of a device we are developing, we do:
git clone https://@/project-url .
This used to work fine. Now I get: fatal: unable to access ‘https://@/project-url’: Unrecognized content encoding type. libcurl understands identity content encodings.
I expect that since an update of the webserver of this gitlab, the content-encoding served now do not include “identity” anymore.

Is there a solution to this problem? It has to be server-side, so the devices in the field will start updating again.
