We will be glad to see your feedback about Network inspector UI. Below there is a survey in which you can select the way you consider is the best. We'd like to discuss which way of displaying network requests data is more preferable to be implemented. Request header, response headers, response body and query strings parameters are extensible, this allows to show only needed information. If a user click on a row, details data of the request will be shown below the row.ĭetails data of the request contains general request data, request and response headers, response body and, optionally, query strings parameters. This is a prototype of the main page of the inspector. Below there are prototypes of UI of the inspector. We suppose that the Network inspector page should be opened at the second editor column in VS Code, so users could see the application code and requests data at the same time. We made up prototypes of UI of our Network inspector. We could create a web client for our Network inspector backend and run it inside the VS Code webview. If this way is chosen to implement displaying of network requests data, we will process that data to show only useful information properly. Microsoft 365 connectivity can be optimized by implementing a combination of approaches like network route optimization, firewall rules, browser proxy settings, and bypass of network inspection devices for certain endpoints. Below there is an example of printing raw request data. However, in this case our network inspector outputs will mix with some other VS Code messages. In the console we can open and hide properties, this allows to show information in more readable form. The screenshot below is just a draft, which doesn't contain all the information about the requests. In this case, all the messages are printed in their full size. We later discovered the customer had recently updated the firmware version of the firewall which included a fix for port protocols “Port protocol protection now drops all packets for unallowed protocols as expected.” Hence why the issue had only recently started occurring.We have investigated ways to display network requests data in the extension and found out the following three ways to do it: This proceeded to resolve the intermittent issue. To solve this the default HTTP+S service was removed and a custom one added for ports 80/443 with the “Action for prohibited Protocols” set to “No Protocol Detection”. A forwarding rule was setup to route internal traffic out to the internet via HTTP/HTTPS, fairly standard practice for client networks however the default HTTP+S service being used had the “Report” action for “Prohibited Protocols” configured within the Service Entry Parameters. We played with disabling the IPS system temporarily and discovered the calls issue went away, with this in mind we attempted to create an override in IPS for this traffic and then re-enable it however discovered that this particular alert is not something you can simply override. STUN is used to resolve the public IP of a device running behind a NAT, to solve problems such as one-way audio during a phone call or phone registration issues when trying to register to a VoIP or an IP PBX residing on a different network. Some research later we discovered the STUN protocol is used in several different network implementations, one of which is VoIP. We identified the on-premise Barracuda F180 firewall had the IPS (Intrusion Prevention System) enabled and proceeded to check the Threat Scan logs, Within the logs we spotted numerous entries for “Unallowed Port Protocol Detected” for the STUN Protocol all appearing to come from the Microsoft Azure Data Centre. A Barracuda F180 firewall separates the internal and external network. Users are housed in Teams Online however calls are routed back on premise via an SBC then back out to the internet. We’re trying to get you back on the call.” A customer reported that Teams calls would intermittently “Drop” at random points in a call with error “Hold On, looks like something went wrong.
