      The user mentioned that he had correct key but still he got "Invalid otp" error "sometimes".

      I think this could be most likely due to time differences on the server.

      Please call or whatsapp me.....I think I might be able to help.

        Definitely a bug. Most likely either all or some of the servers which are involved in validation do not have their time synced with standard internet time.

        Please fix this asap. It is becoming difficult to handle clients with so many issues happening with Smart API.

        Our TOTP generation logic is working absolutely fine for all brokers. As the algorithm is common for all brokers, it should have worked on Smart API as well. But it is failing intermittently.

          Still it fails "intermittently" ...... got no clue what is happening on your server.

                  @StocksDeveloper I can integrate python solution in any language.If you wish to do so reply me on utsav.moradiya3@gmail.com , instantaneous code fix. Before admin releases a solution in language, several algo traders have already adopted this temporary method.

                          @admin Still errors coming. We have already provided many suggestions. Could you please help us understand what fixes you have done? Did you make sure that all your server timestamps are matching with Standard Internet Time?

                          Or was there no fix done?

                            Hi @StocksDeveloper , all our servers are synced with standard time properly and we accept upto 3 time periods - past, current and future.

                              @admin There's no way for us to find the cause from outside. The errors are still happening.

                              We have added multiple retries on our side to avoid this error. Now this is a workaround.

                              Another workaround would be to avoid login again and again. Our session timeout for angel is 50 mins. That means if there's 50 mins of inactivity, we will relogin to angel account. If you tell us exact time of session expiry on your side, then we will increase session timeout on our side. This will reduce login requests & the chances of error.

                              Now these are just workarounds, you need to check what is wrong.

                              One way to check this is writing a piece of code which does login every 2-3 seconds. And run this code for whole day (market hours) on any machine outside of your data centre. This code should never fail, if it does fail then it proves the issue is on server side OTP validation.

                                  The issues seem to have been fixed.

                                  Although we do see errors, but those are mostly for a select few accounts & likely due to invalid TOTP key.
