Hello @iages, Welcome! If you’re not using Kaspersky Total Security, version 21.2.16.590, patch(a) & (b), update & recheck? The Kaspersky software has blocked the port scan attempt: it may be a legitimate detection or a false positive, to find out: log a case with Kaspersky Technical Support, follow the template image as a guide. Include as much information as possible, save the KTS report (you posted as an image), as a text file, attach to the request, images & or a video - if they help show the problem & the URL/link to this Community topic. Support may ask for traces & other data, they will guide you: After submitting the case, you’ll receive an automated email with an INC+12digits reference number, then, normally, within 5 business days, a Kaspersky Technical Support human will communicate with you, also by email, you may continue to engage with the Kaspersky Technical Team via email or by updating the INC in your MyKaspersky account. Please share the outcome, with the community, when it’s available? Thank you🙏 Flood🐳+🐋 Thank you!
