Sophos Network Threat Detection is blocking Cypress automation tool

We run Cypress as our web automation tool and as of the past week or two Cypress has been crashing with the error message: Error: read ECONNRESET at TCP.onStreamRead (node:internal/stream_base_commons:211:20)

As I'm not in control of the Sophos Endpoint Agent I was able to get the IT team to give me the tamper password to test disabling the 'Network Threat Protection' once this was done Cypress was able to run the automated tests properly.

(Stack Overflow thread with others reporting issue)

Has something changed recently and is there someway that Sophos can fix this so I don't have to disable the network threat protection? If you need any info or help with this let me know.

Thanks

Adrian

  • 2021.3 is the release from last year, not all customers have been migrated to 2022.1.x it yet.  If you're not part of the inital accounts migrated I guess you don't have it yet.

    If you contact Support, they can take your tenant ID, which is on the support page in Sophos Central and requrest it is migrated.

    2022.1.1 is what you need for the 127.0.0.1 exclusion to work, 2022.1.0 will not, I believe 2022.1.1 is going to start rolling out tomorrow for those with access to 2022.1.0 already.
