Cannot connect to compute anymore GNS3 3.0.0 RC1

[cristian-ciobanu]

Describe the bug
After upgrading GNS3 to version 3.0.0RC1 I cannot load any existing topology created in earlier 3.0.0 versions.

GNS3 version and operating system (please complete the following information):

OS: ArchLinux
GNS3 version: 3.0.0 RC1
GNS3 server and GUI are running on same machine (bare metal)

To Reproduce
Steps to reproduce the behavior:

1. Start GNS3 systemd service. This completes successfully and I see the server is running
2. Start GNS3 client. I see on the GNS3 console that the authentication from GUI is successful.

POST http://127.0.0.1:8080/v3/access/users/authenticate
Authenticated with controller 127.0.0.1 on port 8080
GET http://127.0.0.1:8080/v3/templates

3. Try to open an existing project. The following warning message is shown:
   Cannot connect to compute 'ARCH-DESKTOP (controller)' with request POST /projects

4. In the GNS3 server log I see these messages repeating multiple times

Please can you let me know what version of aiohttp is installed? thanks.

[cristian-ciobanu]

I have aiohttp version 3.10.3 installed.

[grossmj]

Please try to downgrade to version 3.9.5.

This is what we have in the requirements.txt file:

aiohttp>=3.9.5,<3.10

Thanks.

[cristian-ciobanu]

I have downgraded back to 3.9.5 and now the projects load fine.
Thanks for pointing me in the right direction.

We need to add support for the latest aiohttp
