Comment (by nickm):

 So, I see those warnings happening still, but they happen as part of this:
 {{{
 Jun 20 10:35:55.522 [info] HTTP body from server '127.0.0.1:7000' was
 labeled as Zstandard compressed, but it seems to be deflated.  Trying
 both.
 Jun 20 10:35:55.522 [warn] Zstandard decompression didn't finish: Unknown
 frame descriptor.
 Jun 20 10:35:55.522 [warn] Error while uncompresing data: bad input?
 Jun 20 10:35:55.522 [info] handle_response_fetch_status_vote(): Got votes
 (body size 10366) from server 127.0.0.1:7000
 }}}

 To me that looks as if we tried with both zstd and deflate, and zstd
 failed, and deflate succeeded?  I'll add more logs and try again.
