I have installed the A360 on-premises in my machine.

After the installation.I tried to run a simple bot containing only message box.

It throws the below error

 

 

I tried the below solutions

1.re-install bot agent

2.Update bots to default package

3.clear global cache

 

None of them are working for me.

 

Please help me on this.

Hi ardra,

 

Have you checked whether the device is connected properly or else check the Bot agent Service running successfully or not.

 

If you are still facing  an issue can reach out to me.

1) Login with an Admin user in Control Room URL.
2) Control Room URL should be match from which login has done and one which has added under Administration -> setting -> General.
3) Compared the URL and found that it has added "/#" at the end of the URL as  below

 

4) Edit it and remove "/#" from URL.
5) This should resolves the issue.

@ardra ,

Do you have a self-signed certificate? 

With admin user Control Room, go to Administration -> setting -> General and change the url with https (secure mode)  to http (non-secure protocol) if it was enabled.

@Raul Jaimes 

I don't have the Self-signed certificate.

Url in ‘General’ is http only.

 

Thanks,

Ardra

Let me know if this is your actual scenario: 

1.-You have installed A360 in your control-room

2.-You are trying create a bot in the same VM. Here you are facing the  last mentioned error.

3.-So, you url is 

4.-if you have a self-signed certificate, it probably is with a  mylaptopname 

5.- self-signed certificate  is not required if you are using an http protocol .

in order to progress with your enviroment, please add the mylaptopname in the file host in Windows:

C:\Windows\System32\drivers\etc\hosts

 

 

Restart Automation Anywhere Bot agent and try again.
