Error:

instaloader.exceptions.ConnectionException: JSON Query to graphql/query: HTTP error code 401.

Description:

After a certain amount of time since the initial session creation, the program encounters a ConnectionException with an HTTP error code 401 (Unauthorized). This suggests an authentication issue.

Analysis:

Based on investigation of instaloader's issues, it's possible that the program is relying on a session file that becomes invalid after some time. This could be causing the authentication error. My other theory is that after a certain amount of requests a new session is needed, possibly due to session id.

Possible Solutions

1. Automatic Session Recreation:

• Implement functionality to automatically recreate the instaloader session at regular intervals or when the 401 connection error is encountered.
  • This could be done either reading the file creation, and access times (not sure how well that works cross platform) or by reading the log file for when it was created and comparing with the current date.
  • I'd guess that a good time for session re-creation would be 24 hours.
• This should hopefully ensure that the credentials are not stale and the requests would be valid.

2. Investigate Instaloader issues further:

• Look at more instaloader issues about 401 errors, seeing if anyone has a solution to it, and if they do how that solution can be applied to this program.

3. Error Handling and Retrying:

• Catch the ConnectionException where it occurs and then recreate an instaloader session using browser cookies and retry the program
• If the retried request occurs again, catch the ConnectionException and gracefully exit.
