CoWIN's api rate limit is 100 per five minute for an IP. You need to ensure you don't pass more than that. Each district and each pin contribute to an API call.

Example: Lets say i am searching for 2 pincode. At refresh rate of 5sec, my total requests in 5 min would be 120. [ I will get blocked ] At refresh rate of 6sec, my total requests in 5 min would be 100. [ I may get blocked when there are OTP calls] At refresh rate of 7sec, my total requests in 5 min would be 85. [ GOOD ]

Formula: 5 x 60 x refresh rate / no of api calls

Calculate your API calls and you should be good. If you are using Pincode based search, use option 3 as it will save your calls.

I knew about this and I tried too. I set the refresh rate to 30 sec still this problem persists. 30 seconds is a big number in comparison to 5-7 as you explained but still the problem remains. It logs me out and doesn't let me in for some time.

Please try yourself and respond regarding the same. It's hard to book.

I saw similar issue after updating to the latest code...something is wrong.

I have tried it. If the IP is dedicated to you, the calculations are correct. Your ISP might be NATting IP. Try with a different ISP and check.
