I assume you mean "Failure when receiving data from the peer" in the latter
case. That's what curl_easy_strerror() returns for CURLE_RECV_ERROR.

I would say both errors could indicate that the user has a flaky connection
with something causing problems that messes up the TCP connections for him.

I don't think you can trigger these problems in your application and I suspect
the correlation between these problems and "it works fine in other
applications at the same time" is very hard to judge and are at best a guess
unless you really stort to monitor the traffic and measure what's happening.

I don't think you can avoid these errors in his place. You can only do your
best at handling these errors and retry or work around them in other ways.
