Other webdav clients work properly without timeouts? Zimbra can connect to other drives without timeouts?

3

yes. iā€™m able to access webdav using my MAC and IMAC without any issue. what could be the reason of this issue?

4

i try access to webdav using cadaver cli from the email server also with success. able to manage all the files. Seems like the issue happened to accessing from webmail only.

Here was a similar error:

Not sure if all the fixes are also in NC 11. If you want to test on NC 12, please wait a few days for the NC 12.0.1 release (perhaps try a small test setup first, 12.0.1 contains this fix: https://github.com/nextcloud/server/pull/5386).
