Hi Volkan,

 

might be that you are hitting this issue:

You can try to use an older trex server image (create a new image definition).

 

regards,

My techincal solution steps;

 

1- After logging in to learningnetworkstore.cisco.com, download the refplat_p-2020110-1-fcs.iso file from the download section, the CML-Personal 2.1 content.
*file size 7GB.

 

2- Please open the iso file. Copy the Alpine-3-12-Trex282 folder in the Virl-Base-images directory to your computer.

 

3- Run the Cisco Modeling Labs environment and log in via the web.

 

4- Enter the Node and image Definitions tab inside the Tools tab.

 

5- Click the image Definitions tab then click the Manage button. Select and install the Alpine-3-12-Trex282.qcow2 file that you have already taken from the Upload New Image File.

 

6- Enter the Node and image Definitions tab inside the Tools tab. Back to image Definitions again and press the Add button.
* ID > alpine-3-12-trex282
* Label > TRex 2.82
* Description > TRex 2.82 (based on Alpine 3.12)
* Disk Image > Select > alpine-3-12-trex282.qcow2
* Node Definition > trex

>Finally click to Create Image Definition buton

 

7- Open a new Workbench and Add Trex virtual device from the Add Nodes tab. Before operating TREX, please LEFT on the device and log in to the Simulate tab. Select the TREX 2.82 version from the Image Definition tab, run your device after making the necessary connections.

 

I hope it helps those in need.

Have fun and learn lots
