Describe the bug

I filled out everything by hand, no copy&paste and I get: data must NOT have additional properties
every time i try to set up a stream forward etc. with ssl. if i disable ssl it works.

Nginx Proxy Manager Version

2.12.6

To Reproduce
Steps to reproduce the behavior:
i dont know, it happens no matter what i do. just fill out like usual. it happens with different dns providers, different hosts port and so on i tried everything.

Expected behavior

adding a ssl stream forward

Screenshots

Operating System

using ubuntu + ur docker image + portainer

Additional context

dont know of any logs

[freakyy85]

I also tried Firefox and Google Chrome, both give the same error.

[freakyy85]

I tried readding, editing several fields in different ways. does this error happen if something goes wrong with the dns challenge?

[freakyy85]

I've also checked the logs, nothing in there.

When I use an existing ssl cert in the dropdown menu, it works. but i need one made with dns challenge auth.

[freakyy85]

ive now created a cert manually in the ssl cert section. then i selected that one to use nd its working even without dns challenge.
