Hello!
The following error occurs during testing:

Spoiler: ResponseError

** Activity (main) Create, isFirst = true **
** Activity (main) Resume **

RemoteServer is running (08/06/2020 14:38:03)
Connection successful.

PC-Phone connection via WiFi is OK.
IP Address PC (or Router) - is OK
B4A-Bridge: Connected = is OK
Port XXXXX open in the firewall - is OK

Where else can you look for the cause? ?
Thanks in advance for any ideas ...

Open the 'test' link from the phone browser. Does it work?

Make sure to set the correct ip address.

Welcome back,
Well, when I try to open in the browser on the phone, giving the correct IP, no data is downloaded from the database. Although I admit that it used to work.

I think the DNS Server is to blame. I'm just changing the configuration of the Ethernet - Router, maybe it will help.

No less thank you Erel for paying attention
Best regards.

Hi,
The above problems resulted from the wrong choice of DNS servers and Fireware settings, but another problem emerged along the way, namely:

I'd like to ask the experts
because I do not know if I am right, but when creating a B4A application, both the DBCommand and DBRequest types have to be UNConditionally declared in Proccess_Globals, i.e. in the main activity? Not in any other activity / class / service module.

Best regards.

True. Or in B4XMainPage if using B4XPages.

Thanks for reassuring me, I will check the operation of B4XMainPage one day.
