Developer not able to enter Create for our app

We just hired a new remote developer that is not able to enter our app in Create, but he is able to enter the Showroom in Create. I guess our app is quite bigger than the Showroom app. Error codes attached. Is this purely an internet speed issue?



Does the solution load for you? Is your remote worker outside of Europe (checking for latency/poor internet connection)?

Yes, it works fine for us.

He sits in Bosnia, not the best connection (10Mbps). He was just able to enter with mobile connection at 20 Mbps, so I guess the internet speed is the issue here.
