Hi, all! My library is moving its Koha ILS to an AWS-based server. In development, it was on a standalone laptop. In the testing phase on the AWS server, we have noted that the IP address for logins changes every thirty seconds and staff are signed out from Koha. The staff have to sign in anew and refresh. Whatever the staff were working on -- search, record editing, uploading new records, etc. -- may or may not survive intact. We don't know what causes this, but it's like IP 42.0.2.35 Staff types a search query. IP 42.0.2.35 Staff selects Edit Record from dropdown menu. Sudden change to IP 42.0.2.29 Record vanishes. Login screen appears. New IP 42.0.2.34 Staff logs in anew Staff backs up two tabs (or windows) and continues. New IP 42.02.31 Repeat of what staff intervention at New IP 42.0.2.34 Eventually whatever the staff were working on is accomplished, but logging in anew and reentering the previous steps so often are a bit inconvenient, to state the least. My IT staff doesn't understand this phenomenon. We checked the system preferences, but we haven't changed the timeouts since Koha was initially installed. Has this been reported to the Koha development teams or on this discussion group before? Does anyone have an idea what would be causing this? -- よろしくお願いします。 -- Charles.
