[BUG] HttpClient.Timeout error is back

[AndersRask]

Reporting an Issue or Missing Feature

I have noticed that for site collections with many subsites, I am getting HttpClient.Timeout when calling either using $web.Webs or Get-PnPSubweb

Expected behavior

I was expecting retry-handler to handle timeouts in http calls

Actual behavior

The request was canceled due to the configured HttpClient.Timeout of 100 seconds elapsing

Steps to reproduce behavior

# note Start-PnPTrace enabled to console
# the site has to have a good amount of subsites (+3000!!!)
Connect-PnPOnline -ValidateConnection -Url https://contoso.sharepoint.com/sites/somesite -Tenant $tenantId -ClientId $clientId -Thumbprint $thumbprint
Get-PnPSubweb -Connection $connection -Verbose
VERBOSE: Cmdlet execution started for get-pnpsubweb -connection $connection -Verbose

Mitigation so far is to use Get-MgSubsite -SiteId -Top 4000

$subsites = Get-MgSubSite -SiteId $siteId -Top 4000
$subsites.Count
3192

Hmm, looks like a server side issue, maybe you can use this to change the timeout value.

$env:SharePointPnPHttpTimeout = 300

or

$env:SharePointPnPHttpTimeout = -1

Doesn't seems related to rate limiting , might be something else.
