Hi Dan,

thank you for tat hint! It took a while to get the tool (curl-impersonate) up and running but it didn't solve the issue this time. Also, I am using libcurl - so it would have been a temporary solution only. Meanwhile its magically working again for all connection. I assume Cloudfare changed the backend (see the other answer of mine in this thread).

I am not very happy about the situation and noticed you are one of the libcurl team members, too. I know it should actually not be your business, but if you can integrate some functions in libcurl or provide some guidelines that help in such cases I would be very grateful.

Once again thank you,
