The Blogger Login Problem And The Maximum MTU Setting

Recently, we've been seeing a small but steady trend of complaints about logging in to Blogger.
I can see my blogs, but if I try to Log on: "no can do" - it's like blogger.com does not exist.

After waiting for ages, the browser finally lets me know that the page cannot be viewed; suggesting that I may, perchance, have misspelled the address, or that the site may be "down".

or
I have tried different browsers, I have installed updates, I have changed and tried out every single setting, I have reset and uninstalled updates and changes on my computer, I have tried everything, and the browser refuses to go to Blogger.com.

or
I can`t log in to my blog. It was no problem yesterday morning,but in the evening and today I can`get in. Just get an error on the page. I can see my blog, but not login to it.

and later, a brief bit of crucial diagnostic detail
Here's what I see
Opera could not connect to the server. Maybe the server doesn`t use the supported SSL-protocol, which is not safe enough for safe communication. The owner of the server should upgrade to TLS.1.0 or newer.


All of these symptoms, taken together in general, and with the latter in particular, point to an MTU setting problem on the blogger computers, and probably to a problem router or server at Google.

Any time you have a network connectivity problem which comes and goes, and which may possibly focus on screens (like Blogger login) that use the HTTPS protocol (TLS 1.0 in Opera language), you should suspect an MTU setting problem. An MTU setting problem is arbitrary and capricious, and comes and goes randomly. One scenario when it will commonly show up is with someone logging in to a server and using HTTPS, because the HTTPS protocol adds information in the packet header, and makes the packets larger.

If your MTU setting is marginal, or optimised carefully for HTTP traffic (which is 99% of your browser activity), and your network is susceptible to an MTU problem, the overhead generated by HTTPS will likely push your network over the edge, and you get the familiar symptoms (well, they're familiar to me, anyway).

Now, it's time for you to check the MTU setting on your computer, and target "www.blogger.com" for the tests.
