problem reading Extension Store json stream

[gferreira]

continuing from Prepolator and MetricsMachine are not listed in Mechanic 2.0

• extensions from the Extension Store do not appear in the list
• the Extension Store json stream URL appears to be correct
• the robofont-3-py3.log file contains the following error:

20/05/2020 14:16:04 >    ERROR > Mechanic >> Cannot read url 'https://extensionstore.robofont.com/data.json'
20/05/2020 14:16:04 >    ERROR > Mechanic >> Error 'Error Domain=NSURLErrorDomain Code=-1200 "The operation couldn’t be completed. (NSURLErrorDomain error -1200.)"

I can’t reproduce it in RF3.3 or RF3.4 (10.13.6)

any idea what could be causing this error? thanks!

the error is happening on macOS 10.10.5

[gferreira]

it seems the problem is related to SSL certificates and macOS 10.10 (?)

the name of error -1200 is NSURLErrorSecureConnectionFailed

ATS and HTTPS Server Trust Evaluation Requirements says:

However, this fine-grained control is not available in older operating systems (iOS 10.0 and older, or macOS 10.12 and older). To maintain backward-compatibility when you use any of these keys, you must also set the value of the NSAllowsArbitraryLoads key to YES, taking advantage of its version-specific behavior. It works as follows:

FYI: RF already has already NSAppTransportSecurity -> NSAllowsArbitraryLoads set to True...

fixed by using an older version of mechanic as this seems to be a SSL certificate issue on 10.10

for 10.10 use https://github.com/robofont-mechanic/mechanic-2/tree/1901e663e1cc63c5485fa0cc05e9a423961560ee
