Unable to connect to the remote server

Hi Eduard,

I see that you are using the Adobe Sign Trial account.

If you are using the account for testing the Adobe Sign integration, I would suggest you register for the free Developer edition of Adobe sign from here Create Developer Account, APIs for custom applications | Adobe Sign

Please make sure that you use the email address which is not registered for any of the Adobe Sign accounts.

The settings are not enabled by default to access the Integration Key in the free Developer account.

I would recommend you contact Pre-Sales team to get the settings enabled.

They will be able to provide pre-sales technical assistance to you.

Please refer to this link Adobe Sign – Plans and pricing for enterprise and individuals | Adobe Document Cloud to get in contact with them.

Let us know if you need any help.

Regards,

Meenakshi
