Hi,
I am trying to install Okta Access gateway on AWS machine, I was able to follow the guide until adding DNS entries into the server and i was able to get Okta Access gateway UI screen (https://admin), and when i try to login with default credentials, i get the following error.
The error message in the tracking Id is : Access Gateway host:[admin] referer:[https://admin/auth/saml2/idp/SSOService.php] error:[System Error] tracking ID:[377a3f462e] details:[Unable to validate Signature].
I have checked the logs in Access gateway server and see the following errors in the logs.
Based on what i understood this is relating to certificates and since i am doing this as dev/ initial exploration stages, i am not sure about getting certificates. Here are my questions
- Is this related ssl certificates issue?
- If yes, i dont have SSL certificates, will self signed certificates work and if so is there any documentation on that ?
I am very new to okta and any help is appreciated.
Thanks.

Hi Krishna,
Thank you for reaching out to us! I investigated exhaustively based on your description and could not find anything that points to a certificate-related issue at the step you are in.
Since something similar happened to me when I first started using OAG, I would suggest you ensure you followed every steps from the guide, without assuming you already did them.
I would suggest you pay special attention to the steps for configuring OAG DNS, since this is likely the cause of the problem. When this happened to me in the past, installing from scratch and carefully following each of the steps took care of the problem back then.
If you still experience this issue after trying these suggestions, please open a case with Support for us to have more resources to better assist you.
