Hi @KingswaySoft - To help out here, can you give a bit more detail about the steps of the process? Specifically, if you’re at the stage of swapping the code for an access token, can you provide the following: - full URL of HTTP request - Method - Headers - body (be sure to redact your ` Less necessary, but you can provide your code snippet too. ---

Hi @KingswaySoft , The only thing that jumps out to me is maybe the URL encoding of your redirect\_uri. Can you double check that the URL isn’t being double encoded? Additionally, can you test this exact request in Postman, outside of the context of your code? Here’s a Postman collection to edit - [https://www.getpostman.com/collections/a231c29e2ec393f87b2a](https://www.getpostman.com/collections/a231c29e2ec393f87b2a) You can import that to postman via File \> Import \> Import from URL. Then, edit the request to include your client id and client secret. Go through the first step of the flow in your browser to get a new code parameter, and then copy/paste into the Postman collection and Post. Let me know the results. ---

Hi @robertainslie , I’m sure the redirect\_uri is not double encoded. I have just tried in Postman and got the same 500 error result. This error only happens to a particular HubSpot instance, the portalId is 163004 if it helps for you investigation. ---

Hi, @KingswaySoft. Thanks for your patience. I’ve run nearly 40 tests today with your auth URL, different accounts, and different users and have an update! I can consistently reproduce `500` errors from [this endpoint](https://developers.hubspot.com/docs/methods/oauth2/get-access-and-refresh-tokens) after authenticating your app with a **Super Admin** who has **Sales Professional** or **Enterprise** access — the same permission set as the user in account **163004**. Once a user with both the **Super Admin** and **Sales Professional/Enterprise** roles triggers a `500` error, they are unable to connect the app under any circumstances. Revoking the roles and even changing the auth URL have no effect — the endpoint will continue to return `500` errors for that user. Curiously, other combinations of roles work perfectly. An **Admin** with **Sales Professional/Enterprise** access can connect and disconnect the app any time, as can a **Super Admin** with no **Sales Professional/Enterprise** seat. I can continue to dig into this issue. In the meantime, could you have a different user with the appropriate permissions in account **163004** connect your app? (Depending on your client’s needs, either of the combinations above will work.) Please let me know if I can clarify further. ---

Hi @IsaacTakushi , thank you for the update, glad to hear you can reproduce the issue. We have suggested our client to try with a different user for now, please keep us posted if you find anything else. We are eager to know the root cause of this issue. ---

Hi, @KingswaySoft. So sorry for not being in touch. This should now be _fully_ resolved. We found that when all possible [scopes](https://developers.hubspot.com/docs/methods/oauth2/initiate-oauth-integration) were requested _and_ granted, it caused a timeout that triggered the `500` errors. This issue was rare because it only occurred when users had access to tools like transactional email, which most HubSpot customers do not have. One of my other colleagues will notify the owners in account **163004** directly. Thank you for your patience throughout this long process. ---

Hi @IsaacTakushi . I’m having the same issue when trying to get an access token for a test app I’m trying on a dev account. What was the solution in the end? Sorry, ignore me. Was being dumb and found a typo.
