Instagram Standalone Not Working

[jrpetersjr]

📜 Description

Whenever I try to use instagram standalone no matter what I do I just get a page not found error:

The domain (with my actual domain replaced with mydomain) that is in the address bar is:

https://www.instagram.com/oauth/authorize?enable_fb_login=0&client_id=undefined&redirect_uri=https%3A%2F%2Fpostiz.mydomain.com%2Fintegrations%2Fsocial%2Finstagram-standalone&response_type=code&scope=instagram_business_basic%2Cinstagram_business_content_publish%2Cinstagram_business_manage_comments&state=UwTIDv

👟 Reproduction steps

1. Go to calendar
2. Press Add Channel
3. Click Instagram (standalone)
4. Log into Instagram
5. See error on screen

👍 Expected behavior

I should be able to connect postiz to any of my instagram accounts.

👎 Actual Behavior with Screenshots

The above image shows.

💻 Operating system

🤖 Node Version

I am also running into this issue

if I use the url from here

I get this

but If I just use the redirect URL by itself I also get the above not sure how to proceed

[nevo-david]

Are you using it locally? You would need to use "https://redirectmeto.com/"

[codetechninja]

Hey @nevo-david I am using it Locally, I will check that out thanks

I too am running into an issue during add. Using a public server.

Application error: a server-side exception has occurred (see the server logs for more information).

The redirect URL is identical to expected.

https://postiz.example.com/integrations/social/instagram-standalone

If you try a different redirect URL (for testing) it throws a different error on the IG end.

[SuperMeepEnby]

Did you manage to make this work? I tried adding the redirectmeto part in front of the redirect URL like so https://redirectmeto.com/<my_server_url> but it does not work either.

I am also running into this issue

if I use the url from here

I get this

but If I just use the redirect URL by itself I also get the above not sure how to proceed

I got this same screen when trying to connect an instagram account. After adding some console.logs to the back-end code, I discovered that the back-end makes an intermediate request to graph.instagram.com, which is a domain my DNS Adblocker happened to be blocking. After whitelisting this domain, connecting my Instagram account worked.

[enisbudancamanak]

I found the solution. I updated the .env file, but I also had to edit the Docker Compose file to include the missing .env variables.

In this case:

- 'INSTAGRAM_APP_ID=${INSTAGRAM_APP_ID}'
- 'INSTAGRAM_APP_SECRET=${INSTAGRAM_APP_SECRET}'

In Coolify, you can find these under "Edit Compose File".

[KERMANEwalid]

just change the OAuth redirect URIs on meta app

from https://postiz.example.me/integrations/social/instagram to https://postiz.example.me/integrations/social/instagram-standalone
