Relay Server unable to connect with backend farm

[Former Member]

Hi Everyone,

Environment.

SUP 2.1.3

Relay Server: iAnywhere Relay Server Version 12.0.1.3423

Accessing BO Report via Iphone/Ipad getting SUP Error 552, settings on BI mobile app,

-connection name: SUP

-Security Config: COBI

-Server: my.company.uk

-Port: 80

-Farm ID:  <suphost>.msg

-userid/pass: BO uses AD Authentication.

Action taken,

1. rebooted relay server

2. rebooted sup server

3. outside of company network, im able to ping get the IIS7 image when execute my.company.uk / ip address

Rebooted SUP/Relay server, still having the same issue.

Then, deleted the SUP connection on the mobile device app and recreated after killing the background process , still no go.

Everything was working perfectly fine, up to this point when we are having trouble.

Looks like SUP having trouble to establish connection to Relay Server...

Appreciate any leads to get this fixed, Thanks again.

Ramesh,

We had somewhat similar issue.

The solution we opted was, upgrading SQL Anywhere Mobilink Server to 12.0.1.3750

Try downloading patch EBF 20512 and applying on SUP server.

hi Ramesh,

we host a webinar tomorrow, Thursday Oct 10: Relay Server set-up, config and troubleshooting.

You might find that interesting?

Details are on this page: http://scn.sap.com/docs/DOC-43425. You'll find a calendar file as attachment that contains all dial in details.

Recording will be published via that page as well.

cheers, Jan

Hi,

Does your local connection works Ok? (bypassing relay server)

Please take care of the following:

Devices on 3G/4G network not able to connect to Unwired Server.

A connectivity issue may occur between the device and Unwired Server. The current client libraries use a protocol that supports HTTP chunked transfer-encoding only. 3G/4G traffic might, in some cases, be subject to content filtering and convert the messages from chunked transfer-encoding to fixed content-length if the communication is done via standard HTTP ports, which most commonly are 80 and 8080. Since the client application can support only chunked transfer-encoding, the communication cannot be established. In effect, a response cannot be sent back to the server indicating that the device is online.

Note: For devices on WiFi networks, the connection between a device and Unwired Server establishes without error.

Workaround: Use a non-standard HTTP port (any port other than 80 or 8080) or an HTTPS port, that is, 443 for Unwired Platform client communication from devices to the Relay Server or external load balancer, whichever one is used, in the DMZ.

So you can try connecting to relay server using any port other than 80 or 8080.

Hi Erick,

MobileBiService.war is not configured since our company dont allow VPN software on our mobile devices. Therefore direct connection to BO wont work, so it has to go through the Relay Server im afraid.

I just notice that, i managed to connect on the mobile device to relay and all, but when try to view some of the report getting error, apparently the connection work intermittenly only.

Also when i use port 443 over 3G and company Wifi, im getting diffrent error code:

Accessing BO Report via Iphone/Ipad getting SUP Error 552, settings on BI mobile app,
-connection name: SUP
-Security Config: COBI
-Server: my.company.uk
-Port: 443
-Farm ID:  <suphost>.msg
-userid/pass: BO uses AD Authentication

Getting error, SUP: 515

when use port 80, getting connected intermittenly but when viewing the BO report getting SUP 552

Hello,

So when using the 80 port you are able to register your device on SUP? You see the Application Connection on SUP Console? According to our experienced getting connected intermittenly during the initial syncs of devices bring you a lot of problems.

It is a must to avoid intermittenly when using 3G please check that the telcom operator signal is Ok maybe moving to another location.
