uploading files to OneDrive

Question

Hi team, Joe here from WPvivid team, we are the developer of WPvivid Backup Plugin - https://wordpress.org/plugins/wpvivid-backuprestore/. We've supported OneDrive as one of remote cloud storage for years now. In our plugin, we use OneDrive's php sdk for uploading backup files to OneDrive, when uploading a file, we create a upload session first - "https://graph.microsoft.com/v1.0/me/drive/root:/'.$path.':/createUploadSession", then use the returned uploadUrl to send an http request to upload the file to OneDrive. The method of sending the http request is php "curl_exec". Recently we found on some servers the uploading process would get stuck, it is not stuck every time, but a certain time after uploading some chunks, the "curl_exec" would not returned a result. Finally, the script execution time of the server would be reached and the uploading process would time out, then our plugin would retry the process by resending the http request. If this is repeated, the uploading process would be successful in one of the retries. We have checked with the server proviers and they said that their servers have no limit on the number of http requests to be sent or the amount of data to be uploaded each request. So, do you have any idea what would be the possible reasons for the http issue? The chunksize we set to upload by each http request is 2MB. We also have tried reducing it to 512K, but that does not solve the issue. Please note that this issue is not occuring in most servers, only on some servers, for example, the server providers are WilkinsIT Solutions（Wilkins IT Solutions- IT solutions provider Durham https://wilkinsit.ca/）and https://www.20i.com/. Thanks for your time in advance!
