I’m currently developing a Custom GPT and am using an 80 MB file for its memory. However, every time I attempt to upload it, it displays an error message stating, “Unknown error occurred.”
I suspected this issue may be related to the file itself, however, I’ve successfully uploaded the same file in a regular chat conversation. Therefore, I’m at a loss for what could be causing the problem. Could you please provide some guidance on how to resolve this issue?
Hi @gprooney

These types of issues can vary, and there may not be a single solution since the root cause is unclear.
You can try the following steps:
If you’re using a VPN, turn it off.
Clear your browser’s history and cookies.
Disable all plugins or extensions in your browser (e.g., antivirus, malware blockers, ad blockers, etc.).
Restart your browser.
Log back into ChatGPT.
Additionally, you can try using a different browser and follow the same steps outlined above.
