KNX ETS6 File upload problem. Max. size is reaching…

Configuration
1

I tried to upload my newest ETS6 configuration file to Home Assistant and got the following upload error (see attached file).
With smaller file size it worked out fine, but a lot of group addresses are missing now.
I couldn’t find any way in ETS6 to reduce the size of the .knxproj file.

Could anyone help?

If you have a reverse proxy in front of HA check if that one might be limiting in regards to the filesize

Thank you very much for this answer. This fully solved the problem. Here the new timeouts i placed in the nginx config:

server {
  listen 443 ssl;
  http2 on;
  ....
  location / {
    client_body_timeout 300s;
    proxy_read_timeout 300s;
  }
}
