Giving proxy service as API End point causes an error

Buddhimala Ranasinghe
Hi All,

I have a deployement where I have an API in APIM and a proxy service in EI. I'm creating an API to have this proxy service as API EP. But when I tried to give the url of the proxy service that I have created, I'm getting the following error.

Re: Giving proxy service as API End point causes an error

Firzhan Naqash
Hi Buddhima,

Since timeout has happened, which means the server/machine couldn't resolve the hostname. Can you change your hostname to localhost from buddhimala-ThinkPad-X1-Carbon-5th, and try the scenario again?



Regards,
Firzhan
