I saw that there was another post earlier this year for this same issue without a resolution.
https://community.meraki.com/t5/Dashboard-Administration/Meraki-Dashboard-Integration-with-enterpris...
We spun up an Orion server in AWS.
I have followed the following instructions for monitoring Meraki APs in Orion.
https://documentation.solarwinds.com/en/success_center/NPM/content/npm-monitor-meraki-devices.htm
I see in both the Firewall information that API requests go to api.meraki.com. However, when selecting "Meraki Wireless:API" in Orion, it defaults the Polling Hostname to dashboard.meraki.com and it is greyed out. The hostname cannot be change to api.merkai.com.

When I add the API key, I get an error message that it "Failed to get a list of organizations". To rule out an issue with the API key, I revoked the previous key and generated a new one. Both did the same thing.

From the same host that is running Orion in AWS, they have brought up a web browser and are able to get to dashboard.merkai.com. I don't believe that 443 outbound from the AWS host is being blocked.
I also looked at Solarwinds support pages. For older versions of Orion (12.1 and 12.2) they noted issues with TLS versions. We are running a 2020.x version. Their other note was setting up Orion to use TLS v1.0, but it looks like Meraki does not support TLS v1.0 since 2018.

Has anyone ran into this issue and found a solution? I am going to go back to my AWS team and see if there is an access policy there that may be blocking this.
