Trying to connect to my sandbox from my ec2 instance and I keep getting error:
Error connecting to Weaviate: Could not connect to Weaviate:Connection to Weaviate failed. Details: .
How to check what exactly is the error?
I have verified the credentials and they all work locally.
I have also checked my ec2 security rules and I do have inbound and outbound in port 443.
hi @thinkmariale !!
Welcome to our community 
Tip: for any issues on a cluster hosted in our Cloud, you can support at Weaviate Cloud
Will this error happen on a local machine? If not, this is probably something on the ec2 side.
Can you do a curl on that https endpoint?
Also, can you share the entire stack trace?
Thanks!
Hi! yes I am able to curl.
I was able to solve the issue by toggling on and off the CORS value in the Sandbox dashboard. and then it worked.

@thinkmariale One question, what client/language are you using?
This error message was not giving away the root cause. I would like to investigate so we can try making it more descriptive.
Thanks!
