That Pinterest’s error — “Upstream Connect Error or Disconnect/Reset Before Headers. Reset Overflow” — usually isn’t something wrong on your end, but instead points to an issue with Pinterest’s servers or the connection between your device and Pinterest’s backend.
When this happens on Pinterest, it’s a common problem and typically not an issue with your device or internet connection. According to user reports on platforms like Reddit, this error frequently appears when Pinterest is experiencing a widespread outage.
It comes from a reverse proxy/load balancer (often Envoy) when:
Pinterest’s server closes or resets the connection before sending HTTP headers.
There’s a timeout or overload on their backend services.
The connection is reset due to too many concurrent requests (“reset overflow”).
Possible Causes
Pinterest server-side issue — outages, maintenance, or backend overload.
Network instability — packet loss, slow connection, or VPN/proxy interference.
Browser caching/cookies corruption — old session tokens or bad cached redirects.
Too many requests in a short time — Pinterest rate-limits excessive calls.

What You Can Try
Check Pinterest Status
Visit https://downdetector.com/status/pinterest or Pinterest’s Twitter to see if there’s an outage.
Refresh or Retry Later
If it’s a Pinterest-side issue, it usually resolves in a few minutes to hours.
Clear Cache & Cookies
Especially if you get the error repeatedly on login or browsing.
Disable VPN/Proxy
Some upstream servers reject requests from certain IPs.
Try a Different Network
Switch from Wi-Fi to mobile data or vice versa.
Use the Pinterest App
If the web version errors, the mobile app might connect differently.
If Pinterest is having backend trouble, there’s not much you can do other than wait — but if the error is unique to your device or network, the steps above can help isolate it.
