Synchronisation works fine on MAC , but failed on IOS (webdav)

[mashimarocbq]

I use my own NAS as a webdav synchronisation destination ，works very fine on my macbook

then I use the exact same parameter on my iphone , but failed

when run "check synchronisation configuration" ,it shows "network request failed" error.

why ? I'm so curious , all the parameter are same !

macos: catalina 10.15.4
joplin mac version : 2.9.17
ios:16.1.1
joplin ios version:12.10.5

thanks for your kind answer

Might be the same bug with as I already reported in October last year for the iOS version in combination with WebDav. Unfortunately I never got a reaction from the development team.
