SAP Advantco REST Receiver adapter - Error- Authentication state already initialized



I have checked in the forums and have not found anything related to the issue so i am posting this issue here. Please help as this started only a few days back in production. We have a File (FCC and mapping) to Advantco REST Receiver adapter. HTTP is POST. However, now for the last few days, the channel goes into error as below-

Error: Authentication state already initialized (Software version: 1.0.13)

Message log gives the below error details and after few attempts through out the day, the file is processed and sent to the receiver URL-

07/07/2019 11:17:35.023 PM Error Message could not be forwarded to the JCA adapter. Reason: Permanent error: Adapter call failed. Reason:
07/07/2019 11:17:35.024 PM Error MP: exception caught with cause
07/07/2019 11:17:35.038 PM Error Exception caught by adapter framework: {0}
07/07/2019 11:17:35.038 PM Error Transmitting the message using connection File_ failed, due to:
07/07/2019 11:17:35.068 PM Error Message status set to FAIL

We are on PI 7.3 single stack and did not have this issue with this flow a few days back. This is the only flow going into error with the above error. In one of the discussions (non SAP PI) the solution was given as to check the HTTP Client version for the target and to upgrade to version 4.0 from 3.x

I have not been able to identify why the issue is happening. Can you please advise?
