I have two FreePBX 15 servers running.   I have setup (I think) a warmspare backup on the primary server.  When I run this backup I get the following error at the end of the run:
`Warmspare enabled for this backup
We Have triggered an API to restore the backup on Spare Server
In Pest.php line 232:
Protocol ttp not supported or disabled in libcurl

I have looked around and so far can not find anything about this error.  The backup file does appear to be on the warm spare.
