It's been MONTHS since I last checked the market, let alone my inventory. Now Steam is having this error and the last time I told Steam Support this (which was a few weeks ago), all they gave me was: "Hello,

Thanks for reporting this.

The error indicates that you are sending too many requests to the game's item servers. This most often happens when a browser extension is gathering information about items on a page, or when an IP address is shared across multiple accounts, which often happens when using a VPN, especially peer-to-peer VPNs.

Unfortunately, we have no way of removing these restrictions. We recommend removing any extensions that automate item and inventory activity and disabling all VPN usage. Please note there may be a delay of up to one day between removing the extensions and being able to browse the market or Steam inventories.

We aren't able to offer any assistance with this issue, so this ticket is now closed. If you have an unrelated issue, please open a new help request, and we will be happy to help.

Steam Support"

Is there any other way to fix this so I finally sell some stuff from my inventory?
