Check if my networks are rate limited

nearly half of my requests to ends with error "TCP connection reset by peer"

curl -s -v > /dev/null
  * About to connect() to port 443 (#0)
  *   Trying
  * Connected to ( port 443 (#0)
  * Initializing NSS with certpath: sql:/etc/pki/nssdb
  *   CAfile: /etc/pki/tls/certs/ca-bundle.crt
    CApath: none
  * NSS error -5961 (PR_CONNECT_RESET_ERROR)
  * TCP connection reset by peer
  * Closing connection 0

Other half ends successfully.
I've tried from multiple ip addresses from networks,, there were different OS and network configurations. Look like i'm hitting some rate limit. My service do not make a lot of requests, but i can't check all other services from these networks ((
Please can you check if i was rate-limited?

A post was split to a new topic: Connectivity issues

Hi, @m.laletin,

We're not blocking or rate limiting your IP addresses, but your report looks like it's related to this problem that we're investigating: API service disruption for Russian subscribers


Hi, @m.laletin,

Could you please show us the output of a traceroute to Feel free to either post it here or send it to me as a direct message.


We believe the network routing problem from the St. Petersburg, Russia region is now resolved. If you're still having trouble, please let us know. Thanks for your patience!


Thank you for your replies. Problem self-resolved next day, 6 January. Do not know what was the cause. I've should have checked traceroutes, but i didn't. My traffic was from Moscow btw.

The problem was strange. I've got TCP connection reset by peer, right after tls client hello was sended (after tcp connection was established).

I hope it will never happens again.
