| I was having the chat messages from the App Wallapop, blocked whenever connected to my local wifi network. | |
| I would disconnect from the wifi and connected to the cell service it would work. | |
| Searching online the Keywords "Wallapop network port chat" gave no useful result. | |
| Searching for App network usage traffic keywords landed me to the following Q/A : | |
| https://android.stackexchange.com/questions/203868/how-to-view-network-traffic-requested-by-a-specific-app | |
| This led me to test the following OpenSource App [PCAPdroid - network monitor](https://play.google.com/store/apps/details?id=com.emanuelef.remote_capture), https://github.com/emanuele-f/PCAPdroid | |
| This creates a local VPN and views the App requests. | |
| I saw that Wallapop requests connections on port 53 443 and 5222 | |
| Checking the router I saw that this port is not open on the firewall. | |
| It appears as that this is | |
| Service Name Port Number Description | |
| xmpp-client 5222 XMPP Client Connection | |
| xmpp-server 5269 XMPP Server Connection | |
| [more details here](https://www.speedguide.net/port.php?port=5222) | |
| So I went to the firewall settings of my router and opened the port 5222 and the chat now appears to be operating normally | |
| --- | |
| Local testing from the PC if the port is open was done using the following: | |
| > nmap -p 5222 portquiz.net | |
| Starting Nmap 7.95 ( https://nmap.org ) at 2024-08-07 00:53 Romance Summer Time | |
| Nmap scan report for portquiz.net (35.180.139.74) | |
| Host is up (0.047s latency). | |
| rDNS record for 35.180.139.74: ec2-35-180-139-74.eu-west-3.compute.amazonaws.com | |
| PORT STATE SERVICE | |
| 5222/tcp open xmpp-client | |
| Nmap done: 1 IP address (1 host up) scanned in 0.85 seconds | |
