i have problem syncing with nextcloud client runnning on debian buster (4.19.0-6-amd64) since client version 2.6 with my internet service provider, this is quite particular:
i can connect with 2.6.x client when using wifi via a smartphone, but it refuses when using my isp connection (which name is Free)
i can connect with browser when using wifi via a smartphone or my isp provider connection,
no problem too when i m near the server on same local network
i checked the mapping and firewall, nothing seems to be wrong since it works with firefox browser
does someone have same problem?
