XF 2.1 RSS Feed Importer Curl Error

[rfc0001]

Anyone know what the cause/solution is for this error?:

Error message: cURL error 2: easy handle already used in multi handle (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

This is preventing RSS Feed Importer (Feeder) from importing feeds.

I've applied all OS/software updates to my server and bounced the box and no dice. I've looked at the referenced site and just has the same description which is not meaningful to me.

I'm seeing tons of people reporting this error in general and even the identical error with guzzlehttp:

GuzzleHttp\Exception\RequestException: cURL error 2: (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

PHP Fatal error: Uncaught GuzzleHttp\Exception\RequestException: cURL error 2: easy handle already used in multi handle

I am a user not a developer. The developer is not available. This is the Google API library used in Google Shopping Products submission scripts. The scripts worked successfully, every 20 minutes,...

But no real solution other than hacking GuzzleHttp code. The issue seems to have started for everyone at the same time - 3 weeks ago. Surprised more people here aren't seeing the same error, but I guess RSS feed import isn't that common and people don't keep their servers updated

Continuing to research, this looks specific to CentOS 6 and/or WHM/cPanel and/or GoDaddy VPS. Hundreds of posts on this issue, but nobody really has a clue what broke. There's a hack to the GuzzleHttp client config and that's about it.

Here's the issue logged at guzzlehttp's github:

upgrading libcurl from 7.69.1 to 7.70.0 seemed to fix this issue.
