Scenario works in Selenium IDE but not in Asqatasun audit!

I have a recorded scenario with Selenium IDE which works fine while running it. I’m running different scenarios (different pages to visit). Sometimes the audit works fine on Asqatasun, but other times, even if it runs on Selenium, I keep having errors while running the audit. Here’s a frequent error :

[Failure: Error communicating with the remote browser. It may have died. / Build info: version: '4.0.0-alpha-5', revision: 'b3a0d621cc' / System info: host: '8568bf62f092', ip: '', 'Linux', os.arch: 'amd64', os.version: '4.18.0-240.1.1.el8_3.x86_64', java.version: '1.8.0_292' / Driver info: driver.version: RemoteWebDriver / Capabilities {acceptInsecureCerts: true, browserName: firefox, browserVersion: 78.2.0, javascriptEnabled: true, moz:accessibilityChecks: false, moz:buildID: 20200817153328, moz:geckodriverVersion: 0.26.0, moz:headless: true, moz:processID: 118062, moz:profile: /tmp/rust_mozprofileUW7poM, moz:shutdownTimeout: 60000, moz:useNonSpecCompliantPointerOrigin: false, moz:webdriverClick: true, pageLoadStrategy: normal, platform: LINUX, platformName: LINUX, platformVersion: 4.18.0-240.1.1.el8_3.x86_64, rotatable: false, setWindowRect: true, strictFileInteractability: false, timeouts: {implicit: 0, pageLoad: 300000, script: 30000}, unhandledPromptBehavior: dismiss and notify} / Session ID: 7b94c771-32c4-4007-bd0f-d88114eb3afc]

I also have another question, I have a website that needs credentials to access it, those credentials appears on a pop-up, and while tapping the username and password, those steps aren’t saved in the scenario IDE, and I systematically get this error while running the audit on Asqatasun :

Dismissed user prompt dialog: is requesting your username and password.: 
Build info: version: '4.0.0-alpha-5', revision: 'b3a0d621cc'

How can I add those steps to the scenario ?

Thank you for your help :blush:
