We’re investigating an issue with our upstream security provider Cloudlfare where login attempts in some regions are unable to login to Syncro. We will share updates as soon as we have more information. For more info follow our status page: Issues signing into Syncro due to Cloudlfare in specific regions - Status Page - Syncro
We have been seeing an Uptick in RU and NK hackers porting through other areas staging attacks. As a result, We have had to block by Geo to Stop said attacks. Blocking by Geo may be causing your Cloudflare login failures as well.
