Hi,

I just downloaded 2.1.30 from [https://apps.ankiweb.net/](https://apps.ankiweb.net/), so I assume this is a stable release. After installing 2.1.30 whenever I try to sync I get the error message  
 ![image](https://us1.discourse-cdn.com/flex002/uploads/anki2/original/2X/3/38bcec7d4867884c4ef681313ebb235973013041.png)  
and all changes couldn’t be synched to AnkiWeb.

The problem would be gone if I downgrade back to 2.1.26. Changes that can’t be synched on 2.1.30 would also be synched successfully after the downgrade. Doesn’t seem to have problem anymore if I stick to 2.1.26, but reporting this might be good.

Probably setting HTTPS\_PROXY will help: [https://docs.ankiweb.net/#/syncing?id=proxies](https://docs.ankiweb.net/#/syncing?id=proxies)
