Are you using the new MLAT client,

From another thread

Please note that I have been advised as follows that a new MLAT client is available which should fix the previous issue

Package mlat-client is updated in our repository using the latest published version from mutability (0.2.11), but ours is "1:0.2.13" just because we need to change version number to 'force' apt-get to understand that is a new version (the code is the same).
Should work for every new installation by now.

Note that the packages are updated only for the latest (current) version of raspbian OS (AKA Bullseye), not for older versions (buster). If we have A LOT of users running older OS's, we can create a package for that.....but my recommendation is to update the operating system.

For those running older versions of Raspbian, compiling the MLAT client from source also fixes this problem. There's another thread here where ABCD567 has detailed the process to compile from source.

I dont understand why RB24 developers dont build and add to their repsitory, the mlat-client ver 0.2.13 for Buster and Stretch? It is very simple task and wont take more than an hour of developer's time.
