I keep getting this error while trying to login through SAP BI Mobile app.
"Connection to the server could not be established; try again or contact your administrator (MOB 06031) (HTTP - 1003) Details: A server with the specified hostname could not be found.
I don’t know what to do? We need to deploy mobile to our external clients and i cant get this to work.

What version of Business Objects are you using? Are you using Android or iOS?
Install a ping app and verify you can ping the server from the mobile device. Try both hostname and ip address. If you can’t reach the server then you you have network issues to get sorted out. If you can ping the server then look at the connection details in the mobile app.

Hi Clarence,
Using BI 4.1 SP2 patch 1
Using IOS
I am able to login through the app IF ONLY i go into the app settings and enter the server url in the security exceptions section where it says “Ignore server trust certificate”. Only then i can log in. However, we cant afford to do that because sap is going to take away this setting in the future release of the app and we need our clients to be able to log in through the IOS app and access mobile reports. Thanks
PS: The security certificate we are using on tomcat is a wildcard cert.

Had a ticket opened with SAP.
Their suggestion? The certificate must be approved and valid from a trusted CA. AND it must be installed on users’ devices 
NycPriya (BOB member since 2010-11-04)
We have the same issue, and we are also using a wildcard certificate. Currently running BI 4.1 SP4. Issues occurs with iOS.
We responded to SAP’s warning messages about removing this functionality indicating that we were unable to get our certificates to work. We have turned on the debug logs in the App, but the information is insufficient to determine why the certificate is not accepted.
UPDATE 12-JUN-2015
We did quite a bit of testing today. I’m now not so sure that the wildcard certificate is the problem. Our wildcard certificates are issued by Go Daddy, so we have had to import the intermediate CA profile into iOS to make them work. After much testing today with a non-wildcard certificate, we discovered that certificates issued with SHA1 encryption are working. Certificates issued with SHA-256 encryption are NOT working.
Could it really be the case that the SAP BI Mobile App doesn’t support SHA-256 encryption? I sincerely hope not, as mainstream browsers are already dropping SHA1 support.
Does anybody else have any experience with this?

I got it working. I bought a separate cert for our dev env. https://bodev.ourcompany.com and did it that from scratch. It finally worked. No more exceptions crap to deal with and no more wildcard cert to deal with. Everything worked out well. Took me 3 tries to do it but it works now. We will be testing for a good few days now. If you need step by step instructions let me know. Our cert for the dev env costed less than $100 for 3 years

Thank you, I needed the moral boost of someone saying “it can be done”
Though … right today we got a “proof of concept” working: an iPhone (iOS) can now use the app and connect to it (through “extranet” )
That sure WAS a moral boost.
But the latest (6.2.19) version of the app on Android still refuses to connect.
complains about a “certificate”.
If you 're using Android, I’m very interested to know how you got this working.
Very interested in those step-by-step instructions (AND surprised that the cert has to be loaded to user machine, if it’s trusted already )

Update
Somewhere in … april 2018 our “smarthone provider” upped the Android versions.
SUDDENLY (as in : I checked the SAP BI app two days after the Android update) SAP BI connected me to our servers
In March I still could not do that.
Up to somewhere in January I had this HTC One phone.
Ggood machine but ageing:
apparently there was NO way to put any Android on it past Marshmallow/6 , due to its processor not being compatible.
So I bought a newer phone, Galaxy this time. It was more in line with what others in our service used so things could be “checked” by a colleague.
The new phone came with Android 7 (Nougat?).
But in January, Februari, March, the SAP BI app did not accept any connection, always referring to “certificate” error.
Same thing I had on the Android 6 (HTC)
The app showed the “demo” that seems to be installed with it, I suppose that uses local data or a “SAP cloud show connection”,
but connecting to our system “via extranet” was still impossible.
Then, when the Android update launched from “proximus” (phone provider) [b]Android 8 /b update, without changing anything on the server, the load balancer, the gateways etc, suddenly I could connect SAPBI app to the system.
Was that “expected behaviour” ?
Does anyone know WHY the Android 6 kept refusing the connection ?
My boss pretends that “it should have worked” but is not clear on what was misconfigured, if that was the case.
