Problem with loading the proton web client webview/page (timeout)

[vladimiry]

Grouping issue for this kind of problem.

I made some changes for 5.1.0, but it appears that the issue is still there, #558 in 5.1.1.

Thanks Vladimiry for the reply.
Tried the 5.1.1 Flatpak. Same problem as with the deb & appimage. Not to worry, 5.1.0 sttill works.

Not to worry, 5.1.0 sttill works.

I didn't make any changes in 5.1.1 related to the proton web client webview/page loading. So since 5.1.0 still works well, it appears that the currently implemented webview/page loading scenario is somehow sensitive to the @electron / @chromium / @angular updates (I used to update everything before every release).

Added short delay before loading that blank.html entry point page. Hope this will increase the stability.

Those who face the permanent "webview" loading timeout issue and running multiple accounts, consider setting up the login/load delay for the accounts, so you load them in a sequence. See the "Login delay range (seconds)" input field in the "Advanced settings" block located on the account edit form. So you set up no delay value for the first account, like 5-10 range for the second account, then 10-15, and so on.

I already had 10-30 seconds on all my accounts, but seem to happen quite rarely nowadays.

Just got this o.o

I am still getting this error message on ElectronMail v5.1.6 on Linux Mint 21.1. Every time I come back to my computer to check my email, I have hundreds of these error messages.
