I just cloned a production site to run in a local environment to test and make sure the site was compatible with PHP7 in preparation for a production server upgrade. For the most part, it seems to have migrated without any issue, except for when I try to check for updates, I get the error:
Craft is unable to determine if an update is available at this time. Similarly, the edition button at the bottom of the dashboard gives the error:
Craft is unable to fetch edition info at this time.
I tried deleting my license key and clearing caches to no avail, but then I checked logs and noticed this error had been showing up:
2018/02/26 23:50:58 [error] [application] Error in Craft\Et::phoneHome. Message: [curl] 35: Unknown SSL protocol error in connection to elliott.craftcms.com:443 [url] https://elliott.craftcms.com/actions/elliott/app/checkForUpdates
I can’t seem to find any other mention of this issue on StackExchange or elsewhere - any ideas? Thanks so much in advance.
