I seem to be getting this message after i updated to Magento 2.1.7 - it only displays on the contact page when someone submits the form.

Invalid response line returned from server: HTTP/2 200

I see this in the magento log file:

main.CRITICAL: Notice: Array to string conversion in /home/xxx/public_html/vendor/magento/module-catalog/Block/Product/View/Attributes.php on line 83 [] []

I was stuck in Magento 2.3.3 extension manager and just replaced

!2 with <2

and it worked.
