@baentsch Could you please look into this?

[baentsch]

@t8m , sure. Problem is that the external CF server changed its behaviour at that port (not running x25519-kyber any more but x25519-mlkem). This will be automatically corrected once the next oqsprovider release comes along doing the same change. But that's 1-3 weeks away as the OQS colleague implementing that is at ICMC...

Is that sufficient or should we do something to fix this faster? The only short-term thing I can think of is removing the test, i.e. either the whole oqsprovider test or a patch within openssl to facilitate that for now (need to check how). Any preference on your side?

[t8m]

I've merged the urgent CI fix but let's keep this issue open until the proper fix is merged.

@baentsch Isn't this done already?

@baentsch Isn't this done already?

Nope. Only a workaround. New oqsprovider release has only recently been done. Will do PR to fix this for good this week.
