Cannot upload; cannot authenticate

Cannot upload

1. <!--⚠️Imgur upload failed, check dev console!-->
2. Dev console:

plugin:obsidian-imgur-plugin:1280 Failed imgur request:  Error: net::ERR_HTTP2_PROTOCOL_ERROR
    at SimpleURLLoaderWrapper.<anonymous> (node:electron/js2c/browser_init:2:49935)
    at SimpleURLLoaderWrapper.emit (node:events:513:28)
uploadFileAndEmbedImgurImage @ plugin:obsidian-imgur-plugin:1280

Cannot authenticate

For trying my luck, I have logged out from the setting panel of Imgur plugin,
and then re-authenticate, but this time on Authorize a user for OAuth 2.0 - Imgur:

Woah there!
The information you sent wasn't quite correct. Please return to the place that sent you to this page and try again.

Hi there, this is really a handy and essential plugin for Obsidian, and thanks for your contribution.

Hi @GJRobert. That's because you didn't specify a valid ClientId. First get a Client ID (follow the instructions on the Imgur plugin settings tab), then authenticate. Please let me know if your issue will be resolved.

Thank you so much for the instruction. I do not recall such a process before or perhaps it was one year ago so I forgot.
Anyway the issue is gone!

It's a new requirement since recent 2.6.0 update

Having shared Client ID for everyone caused a rate limiting issue for everyone (#80)
