Uploading backup TAR archive not possible when file is above 16MB - 'Maximum request body size 16777216 exceeded.'

Technically is not a bug, but the upload size limit is too small, preventing from settings restore in a freshly deployed docker image from an even simple previous configuration. In my case the archive file with the backup was about 39MB.




I suggest to change the value to at least 128MB.

In the official stable docker image release 2026.7.4 the value for change is in:
/usr/src/homeassistant/homeassistant/components/http/init.py
