 << . >>               | << . >> vpn encrypted data over tls |
 << . >>               +-------------------------------------+
+-< . >-------+
|   . clients |

sorry i dont know how to express this in words

thanks for both answers. the second option, one i cant afford.

i did some research, the first the answer is partilly correct ig. for example syncthing offers password protection (https://docs.syncthing.net/users/untrusted.html) and for the bin, it provides client side encryption (https://github.com/HemmeligOrg/Hemmelig.app?tab=readme-ov-file#features) which will protect me even over plain http connection ig. please correct me if im wrong

these are product specific feature, so generally, as you said, no is the answer ig. i wish nextcloud offers something like. thanks again
