Topic: Cannot connect to http server via any mobile device!

[DaveLister]

Hi -

I am running an Apache server (WAMP installation 3.22) and Windows 10.

I can connect to the server fine using the external IP from any desktop / Laptop PC, however - when I attempt to connect via a mobile device - the connection just times out!

So the url goes something like this..

http://82.31.245.89:2048/SomeScript.php

I have disconnected my mobile from the WiFi and used just the mobile providers data network (3G) but it makes no difference.

Also just wanted to say that I configured my router so that I could use the standard port 80 - just in case embedding the port in the url was causing a problem. No change.


Any help would be much appreciated..
Thanks.

While you're running Apache on port 80, connect the device to you're in-house WiFi again and try getting to it through the LAN.

http://[LAN-IP-OF-SERVER]/SomeScript.php
http://192.168.x.x/SomeScript.php

If that works get Apache back on an odd port and try it again using the LAN IP.

If that works then you've got a strange edge case that might be impossible to figure out.

I could imagine an old mobile device not connecting in TLS but not plain ol' http. And if it did fail on https it certainly wouldn't be quiet about it.

When I initially had problems, I tried binding the service to the default port (80) in case it was the port assignment that was causing a problem. However, my router would not let me - here is the error message when I try port forward using port 80..

"The local ports between 80 and 80 on IP 192.168.0.18 have been added as virtual server already, please try another one"

I have solved this problem now - it was a bug in the firmware of the router and have successfully forwarded port 80.

However, I still have the same problem. I can access the server via a PC but when I try an android (mobile) device the connection just times out.

Here is the real url if anyone cares to test it..

http://82.31.225.61/mobile/getdel.php?Deviceid=nt55jnk

You should be able to run the this link (which just return some test data) on a PC but not from a mobile device.

I live in the UK so the "server" will go down shortly (as its midnight here now) but I will leave it on for a couple of hours - then will boot up again tomorrow at approximately 10:00 GMT.

Will be keen to see if anyone can connect (especially from a mobile!)

Thanks

I get nothing. I figure your ISP blocks 80, mine does.

Hi glsnith -

Thanks for trying it for me. Actually it may have been that the "server" was down when you tried.

If you are in San Diago, then the server would have been down from early morning till about 12:30 your time (think you are 4 hours ahead of us hear in Harrogate.)

Anyway, thanks for taking the time to try it. I had a customer (who is in York) try connect and he says he can connect both from PC and mobile. So it looks like its something very strange going on here locally.

I have tried various ports, turned firewalls off and port-forwarding options. Tried it with my Wifi enabled and disabled on my phone and nothing seems to work. I cant even connect from and Android tablet via Wifi! Weird. The only thing I can see they have in common is they are both android devices - but I cant see that being relevant.

Think its time to just find a work-around as its taking up too much of my time now. If anyone has any insight I would still be glad to hear it - as I dont like leaving mysteries behind me

Cheers.

Paul.

P.S Server is running now 09:30 GMT (1:30 your time)

If I go to just the IP address of 82.31.225.61 from My PC, Mac, or Linux laptop or iPhone, I get the XAMPP dashboard.

If I go to the full link you have posted, I get nothing/blank page.

Hello,

I see same result as DnvrSysEngr.
So as port 80 is reachable from outside (XAMPP-Dashbord available) the reason for the blank page (http-code 200 ) might be something within your application (see apache's error-log for hints about php-errors)?

Greetings

OK thanks guys...

Some weird stuff happening this end for sure. I am going to move on - put it down to one of life's mysteries!

Can invest any more energy / time on it. At least customers say they get a result back from script so that's something.

Cheers.
