We need to better analyse the issue, can you contact the networking support and check if they can find a solution as the problem seems weird? Thanks
Good day! I have this issue that we can't access our web service even locally if while connected to an AP that has multiple VLAN implemented on it. The port is gi 1/0/44 is configured as general port where device VLAN 20 is added as untagged ports, this gives IP to all ubiquiti AP we have. Then employee VLAN 10 is added as tagged ports. When mobile devices connects, it can browse the internet, access network shared storage, do remote desktop. However, when trying to access our local webserver through a domain name or through ip address, it gives an error of "This site can't be reached". May I humbly ask anybody to enlighten me with regards to my configuration.    
Can't Access Local Web Server on ports that is on General Mode
