Ensure you have a stable internet connection and check the official Adobe System Status page to verify there are no ongoing server outages before proceeding.
Clear Browser Cache and Disable Extensions
Resolve browser-related conflicts that trigger the 415 error by clearing stored cache data and using a private browsing window.
Corrupted browser cookies or conflicting extensions often interfere with the authentication tokens sent during sign-in, resulting in HTTP 415 errors.
Sign out of your account entirely, then close the current browser tab to terminate the active session.
Open your browser settings, navigate to the privacy or history section, and clear your cache and cookies for all time.
Open a new Incognito or Private Browsing window to bypass any active extensions and attempt to sign in again.
If the sign-in is successful in the private window, return to your normal browser window and disable extensions one by one to identify the culprit.
Update the Adobe Acrobat Application
Outdated desktop applications can cause synchronization and sign-in errors. Updating ensures maximum compatibility with server protocols.

Frequently Asked Questions
What does 'Unsupported Media Type 415' mean?
The HTTP 415 error occurs when a server refuses to accept a request because the payload is in an unsupported format. In this context, it usually points to a browser cache issue or an outdated application miscommunicating with the sign-in server.
Will clearing my browser cache delete my saved passwords?
It depends on your selection. When clearing browser data, you can choose to delete only 'Cached images and files' and 'Cookies', while keeping 'Passwords and other sign-in data' unchecked to preserve your saved credentials.
Can I convert a PDF to Word if I can't sign into my cloud account?
Yes. If cloud-based services are down or blocking your sign-in, you can use alternative desktop software like WPS Office, which processes PDF to Word conversions locally on your machine without requiring a constant server connection.
