Thank you for filling out the template so well! 
Here’s your problem:
[ 26515] ResourceCacheDevice::EnsureFetched downloading resource.rpf (hash 41006f2d936855a874940e8ce639902691818a23) from https://40.115.34.161:30120/files/custom-loadout/resource.rpf
[ 26703] OpenArchive: ReadBulk of header failed
[ 26703] ResourceCacheDevice reporting failure: schannel: failed to receive handshake, SSL/TLS connection failed - CURL error code 35 (SSL connect error)GlobalError: Couldn't load resource packfile for custom-loadout.
I found several other threads with the same issue, but none of them were resolved.
Some things to note:
- Make sure your date and time settings are accurate
- Make sure you can access https://runtime.fivem.net/client
- What country do you live in? (Some country’s are blocking FiveM)
