Hello @hou_roc Welcome to the community 
I suggest regenerating all of these
Then try connecting again. It should work.
Let me know if you still have any problems.
I have put my client id and client secret into the x connector, is “connect my account” necessary as well?
cause from the SS I have put I am having a problem with this part.
also why is the error is about access toekn?
am i not authenticating using oauth2 ? not access and scret?
also, check app permissions like this:
I have done that as well, but still not working.
I have the feeling that’s it could be the twitter ( I have basic plan )
Tried doing the same using multiple simpler connectors, and getting 503 from twitter.
Can anyone else test with their own app?
I think you’re using an outdated workflow here. Actually, there is a ready-to-use X/Twitter node you can use directly.
Also, the API works with the basic plan too.
Please take a look here for a sample workflow http://community.n8n.io/t/post-media-to-x-twitter-via-api-new/90997?u=mohamed3nan
Tried your flow and getting Unable to sign without access token here too:

Well, I’m sure you just need to go step by step.
First:
Second: Regenerate all of these:
Finally: Copy the new generated secrets to n8n and connect.
Thank you, looks like I needed to wait a bit until the added callback URL change in dev dashboard take effect.
I have been having the same issues. I made sure that i have all the right authentication setting in the X developer portal, Read and write and Direct message Read Posts and profile information, read and post Direct messages. I have re generated all my keys and tokens. I believe that there is an issue with x or n8n. Something has changed. I will post my code below with out the keys and tokens.
