DirectAdmin issue with setup WPML in subdomain

[feerdispzoo]

Hello everyone,
maybe can anyone from this forum setup WPML in subdomain and know this issue. I've spent now 2 days, and still not resolve this.


main.com - default English website
pl.main.com - additional Polish language.

I try setup WPML "A different domain per language". When I enter https://pl.main.com then return Not valid. and I cannot move to next step.

WPML cannot support me with this, I read all forum and most people have similar issue and still I not find good solution to resolve this.

For reference:

add this subdomain not as subdomain, but as domain pointer

Thanks for reply with this. Now I remove this subdomain as subdomain and add this subdomain as pointer. Now I again try and still return "invalid". I uncheck option "valid on save" and confirm this without valid. Now When I try enter this subdomain, then redirect to main domain
