Sorry for late response.

Interesting... Can I access the server, or can you provide captured response from the server?

Hi, @nahi!

We're facing the the same error (using httpclient 2.8.x).

I've patched #parse_header method (https://github.com/palkan/httpclient/commit/cb2a3a91d834197d0aa9745cc8c1fe48b7e6d197) to raise a meaningful errors and it looks like it doesn't depend on the target server, more likely depends on network conditions.

Example errors:

Pusher::HTTPError: unexpected line: (size 2)

Faraday::ClientError: unexpected line: (size 2)

It looks like an empty line but has a size of 2. Do you have any idea?

UPD: maybe, the problem is somehow related to Sidekiq and it's multi-threading.
