My dev space does not open

[sameeronweb]

​Dear Team

I am following the Journey "SAP Extension Suite
Development Associate
Certification | C_CPE_13"

I am using a HANA Trial Account to finish SAP Extension Suite Learning Journey and certification. My Dev Space almost never opens and gets stuck in the following error "It's taking longer than expected to prepare your dev space. See Connectivity Troubleshooting" for hours. I have tried clearing cache and cookies, used chrome incognito, IE and Firefox. Nothing helps, out of the last 40 times I have tried it has opened up 2 times. Any help I could get will be wonderful !

Thanks

Sameer
